PrestaShop 1.4.x. Troubleshooter. WSOD (completely blank page) after the dump/template installation

The following tutorial will show you how to resolve the completely blank screen issue after the template installation.

First of all, you need to enable errors reporting on your website.

1) Open the file config\config.inc.php and find the following line:

@ini_set(‘display_errors’, ‘off’);

2) Change ‘off’ to ‘on’, re-upload the file and refresh your page.

If it doesn’t help, go to the next step.

3) Download the following file (error_log.zip), unzip it, open with any text/code editor and add it’s content to the top of your index.php file in the root of PrestaShop installation and re-upload it on your server. Then try to access your website and admin panel.

After this manipulations you will find the file called errors.csv in the folder where your index.php file is located. Download and open the file errors.csv using any text editor, you will find the error log there.

Don’t forget to check the template and engine compatibility. You may find the file readme_en.txt with the engine version in the root of your Prestashop installation.
