Joomla 1.5 PHP fatal error allowed memory size exhausted in libraries/joomla/error/exception.php [SOLUTION]

After a site move (from one webhosting to another) the site reported error 500 internal server error. When checking the logfile the file libraries/joomla/error/exception.php reported that allowed memor size was exhausted. I tried increasing it by adjusting the php.ini settings all the way up to 2 GB without resolving the problem. This is way more than Joomla should need.

The problem was that I had forgot to update the temp and log paths in Global settings to the ones on the new server. The path the site is running under can be found by the menu Help -> System info. Then I adjusted temp path and log path in Global settings and the problem was resolved.

If your site gives you error 500 internal server error, access your Joomla database using for example phpMyAdmin and delete all rows in the jos_session table.

Another solution if the problem is a corrupted database is to repair the database tables using phpMyAdmin.

In configuration.php, also try setting cache_handler=”file” instead of “memcache”.

Joomla t3 bootstrap dropdown submenu not working on tablet and phone

A template based on t3 boostrap framework has a problem when click a menu item where there is a submenu dropping down. The visitor has no possibility to click the submenu item. The problem occurs in the android native browser but works fine in chrome for android. Some reports says the same problem occurs in the iphone/Ipad safari browser too.

To resolve this, go to the templetes in joomla backend and configure the t3 bs. Go to navigation and change dropdown trigger from hover to click (as tablets and phones doesn’t have the possibility of hovering).

Joomla error “Table jf_content doesn’t exist” after migration from Joomla 2.5 to 3.4

I was working on a migration project on site running Joomla 2.5, moving it over to Joomla 3.4. On some pages I received an error screen with SQL errors saying, among other things, “Table jf_content doesn’t exist”.

I found out that the common factor for the pages with errors was that they used the include_content_item plugin. I tried downloading the latest version of the plugin, which was 3.0.12 released in June 2014 supporting up to Joomla 3.3. However I was now running Joomla 3.4 and this didn’t solve my problem.

So I had to start looking for an alternative and found the Articles Anywhere extension which gave me similar functionality. After the include_content_item plugin was uninstalled and replaced by Articles Anywhere my problem was solved.

Joomla com_weblinks not working after upgrade from Joomla 2.5 to 3.4

After upgrading my Joomla 2.5 site to Joomla 3.4 the com_weblinks stopped working. I got error messages like these:

Notice: Trying to get property of non-object in /var/www/SOMESITE/components/com_weblinks/models/category.php on line 87 Warning: Creating default object from empty value in /var/www/SOMESITE/components/com_weblinks/models/category.php on line 88 Notice: Undefined property: stdClass::$url in /var/www/clients/client1/web2/web/webhotel24-2/modules/mod_weblinks/helper.php on line 92
Notice: Undefined property: stdClass::$title in /var/www/SOMESITE/modules/mod_weblinks/tmpl/default.php on line 21 Notice: Undefined property: stdClass::$description in /var/www/SOMESITE/modules/mod_weblinks/tmpl/default.php on line 38

As of Joomla 3.4 the com_weblinks is no longer a core part of the Joomla distribution. Instead it is found in the Joomla Extensions Directory (JED). To try to solve the problem I downloaded the latest com_weblinks from JED and tried to install it in my Joomla 3.4 site. This failed with an SQL error however

After trying to manually delete the weblinks package originating from Joomla 2.5 from the site (by deleting the folders com_weblinks folders and renaming the table ending with the name “_weblinks”) I ended up in a kind of deadlock situation where I wasn’t able to install the new weblinks from Joomla Extensions directory either. It didn’t install due to SQL errors.

The problem with upgrading a weblinks package that has been present during a Joomla 2.5.28 -> Joomla 3.4.0 problems are being adressed here. However, just downloading the suggested pkg_weblinks341 didn’t solve the problem for me either. Trying to install it in my Joomla 3.4 site gave SQL errors about columns images and version already existing in the table ending with the name “_weblinks”. Just deleting the table “_weblinks” gave another error about the table “_weblinks” not exisiting.

This is how I solved it.

Warning! 1) The below solution will have the drawback of deleting all your existing weblinks, but it will get the extension up and running with Joomla 3.4 and 2) make backup of your site and database before you begin!

So my solution was:

  • Using phpMyAdmin I made a copy of the table with the name ending with “_weblinks” to a name ending with “_weblinks_OLDJ25” (just to have an easily accessible backup of the table)
  • Using phpMyAdmin I deleted the columns images and version from the table “_weblinks”
  • I downloaded pkg_weblinks341 and now it was possible to install it using the normal Joomla extension install

Joomla! 1.5 menu items not visible

I was moving a Joomla! 1.5 site to a new hosting server. The site had been running on PHP 5.2 on the prevoius server but on the new host only PHP 5.6 or later was available. Joomla! was version 1.5.14.

After installing the site on the new server, no menu items were visible, not in backend, nor in frontend. I checked the database tables and the menu items were present in the database, they just didn’t show up in Joomla!.

The solution was simply to upgrade Joomla! to the latest verion, 1.5.26, which is compatible with PHP 5.6 (something that I would have done anyway as the next step).

Joomla! 1.5 upates can be downloaded here.

Error 404 when trying to password protect administrator folder in Joomla using Apache htaccess

When protecting the administrator folder in Joomla using Apache htaccess to increase the security of the website (which by the way is a good thing to do to prevent too interested individuals to peek where they shouldn’t), you might get an error 404 message when trying to access administrator and the expected password prompt never appears.

The cause can be that the server is configured to allow user defined error pages stored in for example the error folder. If some of the error files are missing the above mentioned problem can occur. Make sure you have the correct folder name and file names for your error files.

This particular problem occured for me when I moved a Joomla site from one hosting provider to another and by mistake also replaced the error folder with the one from the old hosting provider which had a completely different file name structure for the error message files.

VirtueMart not displaying in Components menu after install [solved]

After installing VirtueMart on a Joomla 2.5 site, it should occur in the Components menu in the Joomla! backend. In my case, it didn’t show up.

The problem can be caused by the Xmap – Virtuemart plugin not being enabled.


Go to the Extensions menu and then select Plug-in Manager.
In the filter box, type "xmap" and press enter.
In the list displaying, check if the Xmap – Virtuemart plugin is disabled (status icon is red).
Then click the status icon for Xmap – Virtuemart so it turns green. Now VirtueMart should be availible in the Components menu.


Enabled VirtueMart Xmap plugin

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.

Problem solved!


[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. 


  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".
