Strange problem in cms admin panel

[FranciscoVillen]

Hi mates,

 

I have never seen this error:

 

In the cms admin panel, the list of cms pages appear but there aren't the name and url of each cms page. When I edit each individual cms page, the info is there.

 

I attach an screenshot.

 

It is in a Prestashop 1.6.0.14 working as a multi shop.

 

Does someone know about this error?

 

Thanks.

 

Best regards.

Hi Mdekker, thanks for the answer.

 

There isn't an override of that controller. There are override of AdminOrdersController.php and AdminTranslationController.php.

 

I have renamed these files adding the character "2" and removed clas_index.php in cache folder and the problem persists, so I think the problem isn't caused by any admin controller override.

 

I have tried too changing the AdminCmsController.php and AdminCmsContentController.php  by the files of the original prestashop1.6.0.14 package and nothing.

 

SOLVED: if I add a new cms page, it appear correctly in the back office. It only occurs with the cms pages that are currently created.

 

I have searched in the database, and the cms pages that doesn't appear, have duplicated null entries in the table ps_cms_lang (attach screenshot).

 

 

Removing that duplicated null entries the problem is solved.
