Same here....

 

Sorry, have just found this post. I've already posted it therefore itself.

 

Apparently I'm not alone we are very curious about the solution

 

EDIT: just replaced both files with files from a functioning shop, without any result.

Hi,

 

just resolved te problem. Open the ErrorHandler.php file in: /vendor/symfony/symfony/src/Symfony/Component/Debug:

use Symfony\Component\Debug\Exception\FatalErrorException;

Line 17 remove ''use'' and save the file. Refresh your site and you''ll see a white screen.

Re-type ''use'' and save again. Refresh and you can access your BO again.

 

On my website it worked. Hopefully it will work for you too!

 

EDIT: With debug mode off the screen becomes blank again...

Hello,

I'm not a PrestaShop programmer but I came here because I had same problem in Symfony2 framework.

I solved the problem by removing my \cache\dev folder and reestarting apache and refreshing again.

 

Hope it helps!

Remove the classes.php and classes.map from the app/cache/dev app/cache/prod  folders
