PrestaShop module TECHNICAL ERROR

On a PrestaShop 1.3.2.3 installation I purchased the One Page Checkout 1.2.2 and installed it. After that I got the following error message when trying to add a product to the basket in the shop front end: TECHNICAL ERROR: unable to add the product.

Details:
Error thrown: [object XMLHttpRequest]
Text status: parserror

Solution: The reason is the web server is running in SAFE MODE and the user owning all the PrestaShop files is the FTP user I use to upload the shop. When installing the One Page Checkout module it will be owned by the user running the web server process (in my case www-data:www-data). In SAFE MODE a php script is not allowed to execute a script owned by another user. The solution is to set the owner of all the order-files in the PrestaShop directory to my FTP-user (including the files installed by the OPC module). In a shell this is simply done by the chmod command: cd prestashop-installation-dir chown -R my-user:my-group order* (Replace prestashop-installation-dir with the real path where PrestaShop is installed and my-user:my-group to the userid:grouid owning the rest of the files in the Prestashop installation.)

Screen is displayed upside down on my laptop with Windows 7

Just press and hold CTRL and ALT and then press the up arrow and the screen will return to it’s normal orientation.

In order to support devices with different orientation you can rotate the screen. The screen can be rotated left (left arrow key), right (right arrow key), upside down (down key) and normal (up key) while pressing CTRL and ALT.

My guess this is going to be the next practical joke at the office ūüôā

/tmp problem when installing plugins in WordPress

When you try to install a plugin in WordPress and get an error message like this:

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/tmp//google-integration-toolkit.tmp) is not within the allowed path(s): (/var/www/XXX/) in/var/www/XXX/web/wp-includes/functions.php on line 2140

Warning: touch() [function.touch]: SAFE MODE Restriction in effect. The script whose uid is 12345 is not allowed to access /tmp owned by uid 0 in /var/www/XXX/web/wp-admin/includes/file.php on line 184

Download failed. Could not create Temporary file.

This is happening when the server is running with SAFE MODE because WordPress will not be able to access paths outside it’s web root. Find out the full path to your web root on the server (a hint is in the error message you just saw). Create a temporary directory within your website path and add the following line.

Edit wp-config.php and add:

define(‘WP_TEMP_DIR’, ‘/var/www/XXX/tmp’);

(Replace /var/www/XXX/tmp with the full path to your temporary directory.)
