Joomla multi language problem when trying to change menu item from ‘All’ to a specific language

When setting up a Joomla site for multilanguage you need to set a default menu item for each language. However, sometimes it is not possible to change a default menu item currently set to language "All". The error message displayed is: 

"Warning Save failed with the following error: The Language parameter for this menu item must be set to 'All'. At least one Default menu item must have Language set to All, even if the site is multilingual."

A solution is to do the following:

  1. Select the menu item by checking the checkbox for it to the left in the menu items list.
  2. Then scroll down to the batch change item (found under the list of menu items).  
  3. In the drop down list "Select language" you select the language you wish to set the menu item to.
  4. In the drop down list "Select Menu or parent for Move/Copy", select the menu where item currently is located in.
  5. Select the Move radio button
  6. Click Proceed.

[Solved] Samsung Galaxy Note II (GT-7105) + Plantronics Voyager Legend bluetooth headset poor audio quality

I recently bought a Plantronics Voyager Legend headset to use with my Samsung Galaxy Note II phone. It worked fine for a day or two, then I started to experience poor sound quality. Especially the person I was talking to had real trouble hearing me. Restarting bluetooth in the Samsung or restarting the Plantronics headset did not help. But restarting the Samsung Galaxy Note II resolved the problem momentarily – after a day or two the problem returned.

Before returning the headset to the dealer I decided to have a look at Plantronics website and found out there are a firmware update procedure availible on their website. To get the update software running on my Windows 8 PC I had to run the installer as administrator. When returning to the update window in the browser (yes, the update procedure is done all in the browser), I found my headset was running firmware version 44 and an update would update it to version 93.

After updating the firmware all quality issues where gone. 

To update the Plantronics headset visit http://www.plantronics.com/us/support/myheadset/updater/

 

[Solved] Joomla JCE editor displays as plg_editor_jce in global settings

Selection lists in the toolbar might also display things like "advanced.h1" and so on.

The cause of the problem seems to be translation files for the JCE editor of an older version are read only which prevented them from being updated to the newer version. 

Solution: 

  1. Uninstall JCE editor. Go to the menu Extensions -> Extension manager -> Manage. Filter the extensions by entering "JCE" in the filer field. About three lines will be filtered out ("Editor – JCE", "JCE editor" and "Quick Icon – JCE File Browser"). Select all three and click the Uninstall button. 
  2. Using FTP access, go to the language folder and into the folder of each language you have installed in the system, like sv-SE for Swedish for example. Delete the file sv-SE.com_jce.xml in each folder (sv-SE is corresponding to the language folder you are working in so unless you are using Swedish, your filename will not begin with sv-SE but something else).
  3. Now go to the administrator/language folder and into the folder of each language you have installed. Delete all files beginning with sv-SE.com_jce* (and again, unless you are dealing with Swedish, your filename will not begin with sv-SE but something else).
  4. Go to Extensions and reinstall JCE.

In the global settings, you will now find "Editor – JCE" instead of "plg_editor_jce".

 

PrestaShop categories block empty after migrating from osCommerce

To migrate an osCommerce webshop to PrestaShop 1.5 I used the migration module from Presto Changeo. It worked just as specified, importing categories, products and customers from a running osCommerce webshop. One important thing before you start is that the module will empty all your existing customers, categories and products in your PrestaShop so make shure you are using it on a new shop.

I’ve been working on the PrestaShop installation for a while so it was not a fresh 1.5 install but had been upgraded from 1.3 to 1.4 and then 1.5 (yes it has not been in production before). This is probably the cause of my problems that occured.

The module works fine even if the osCommerce is running on a different servern than the PrestaShop. I small php file must be uploaded on the server running the osCommerce. The import can take several hours especially if there are many products and images. The script can be running in the background emailing you the progress each 5 minutes. If the mail stops coming or you get an error 500 when running in the foreground you simply must go into the module and click resume each time an error 500 occurs until the import is completed.

After the import I could see the categories, products and customers in the back office but the front office blockcategories didn’t show any products. I found that the problem probably was caused by the support for multistore introduced in PrestaShop 1.5.

Solution: 

  1. You need to access the PrestaShop MySQL databas using phpMyAdmin.
  2. Open the table ps_categories. The id_category 1 is the root category. Find which id the home category has (it will have the field is_root_category set to 1). The home category is probably id_category 2.
  3. Open the table ps_configuration and find the key PS_ROOT_CATEGORY and make shure it has value ‘1’ (the id_category of the root category).
  4. Find the key PS_HOME_CATEGORY and make shure it has the value of id_category for the home category, probably ‘2’.
  5. Go to the back office, in the preferences menu go to the general settings. Activate multi store.
  6. In the advanced parameters menu, go to Multi store. 
  7. Click on the default group and edit your store. Select the Home category as Root category. Save the store.
  8. Go back in the preferences menu general settings and disable the multi store.

Now the categories should display in the blockcategories in the front office. 

Vertical and horizontal center img in div

This example shows how an image (img) can be vertically and horizontally centered inside a div. At the same time it illustrates how to resize the image to fit inside the div.

A live view of this code can be seen here. 

<html>
  <head>
    <title>Vertically aligned img in div</title>
    <style type="text/css">
      #container {
        position: absolute;
        width: 600px;
        height: 600px;
        background-color: lightyellow;
        vertical align: middle;
      }  

      #container img {
        max-width: 80%;
        max-height: 80%;
        margin: auto;
        position: absolute;
        top: 0;
        left: 0;
        bottom: 0;
        right: 0;
      }


      p {
        text-align: center;
      }
    </style>
  </head>
  <body>
    <div id="container">
      <img src="sl-buss-6050.jpg" alt="SL-buss 6050" title="SL-buss 6050">
      <p>The yellow box is here to show the div</p>
    </div>
  </body>

Create custom blog category layout in Joomla 1.5

If you need to customize the blog category layout in Joomla 1.5 you do like this: 

  1. Create the following subfolders to your template directory: 
    mkdir -p templates/yourtemplate/html/com_content/category
  2. Copy blog.php and blog_item.php from Joomla core:
    cp -p components/com_content/view/category/tmpl/blog.php templates/yourtemplate/html/com_content/category
    cp -p components/com_content/view/category/tmpl/blog.php templates/yourtemplate/html/com_content/category
  3. Customize blog.php and blog_item.php in the components/com_content/view/category/tmpl/blog.php templates/yourtemplate/html/com_content/category folder to your needs. These modified files will override the ones in the Joomla core if they exists.

 

Div with width 100% and margins or padding gets wider than 100% [solved]

If a div is set to width (or height) 100% and margins or padding are added, it will be wider than 100% causing the scrollbars to appear in the browser. 

For example like this (click here to view live sample):

<html>
<head>
  <style type="text/css">
    body, html {
      width: 100%;
      border: 0;
      margin: 0;
      padding: 0;
    }
    #wrapper {
      width: 100%;
      margin: 0;
      padding: 0;
      border: 0;
    }
    #container {
      width: 100%;
      margin: 10px;
      padding: 0;
      border: 0;
      background-color: lightblue;
    }
  </style>
</head>
<body>
  <div id="wrapper">
    <div id="container">
      <h1>Div taking more than 100% space</h1>
      <p>It demonstrates a div that is taking up more than 100%. Notice the horizontal scroll bar below.</p>
    </div>
  </div>
</body>
</html>

The solution is to set the inner container width to auto instead of 100%, like this (click here to view live sample):

<html>
<head>
  <style type="text/css">
    body, html {
      width: 100%;
      border: 0;
      margin: 0;
      padding: 0;
    }
    #wrapper {
      width: 100%;
      margin: 0;
      padding: 0;
      border: 0;
    }
    #container {
      width: auto;
      margin: 10px;
      padding: 0;
      border: 0;
      background-color: lightblue;
    }
</style>
</head>
<body>
  <div id="wrapper">
    <div id="container">
       <h1>Div NOT taking more than 100% space</h1>
       <p>It demonstrates a div that is NOT taking up more than 100%. Notice the absence of the horizontal scroll bar below.</p>
       <p>The difference/solution is to set the inner div with width: auto.</p>
    </div>
  </div>
</body>
</html>

PrestaShop subcategories not visible in blockcategories

PrestaShop subcategoriesAfter upgrading to PrestaShop 1.5.3 (and 1.5.4) the subcategories where not showing up anymore in the categories block. The solution was quite simple: 

Just deinstall the categories block in the modules section and then install it again. After reinstalling, it will probably be necessary to adjust the block position.
