Blank page on Administration > Permissions

[patrmich]

Hi,

My shop is built under Prestashop 1.5.6.2.

The shop, BO and FO works properly.

But, I have just realized that when I click on the here below tab, I get a blank page :
Administration > Permissions

I am sure that some weeks ago this page opened properly.
And, in the mean time, I am also sure to have not amended the AdminAccessController.php file

In defines.inc.php, I tried to put on true the here below line :
define('_PS_MODE_DEV_', true);
But no error is displayed on the here after blank page page :
index.php?controller=AdminAccess&token=afbec.....

Of course, I am connected to the Control Panel as the Super admin.

Would you have any idea of what could cause the display of this blank page ?

Thank you in advance for any reply.

Patrick

Can you checkout the php logs or Apache logs? what does it say?

 

In addition, how much ram space are you dedicating for php? 

 

Open up php.ini and search for (ctrl+w) memory_limit, what is it?

I finally found a way to solve the matter (non-opening of two tabs Administration > Permissions and Modules > Positions).

 

I searched whether a module could be responsible for this malfunctioning.

So, I checked the Configure button of each activated module.

And for one of them, themeinstallator module , the click on either Configure or Disable or Uninstall or Update button led to a blank page.

Therefore, I deleted the themeinstallator module from the server.

And after this deletion, both Administration > Permissions and Modules > Positions tabs work properly.

 

The themeinstallator module on my shop was version 2.8.

As far as I remember I never used this module and was surprised to realize that this module could cause tabs malfunctioning.
