White Screen

[agira]

Hello 

 

I'm running Prestashop 1.5.4.1 with PHP 5.5.22. 

 

The shop has been running for almost two years. But when I now add a new product in the backend it happens that after adding new products the front is a white screen. In fact the main front page is still showing but as soon as I click on a category all ist white. The backend is still working. No products can be listed, all is always a white page.

 

When I compare the backups of the database it can happens that with just adding approx 4 new products the database is growing by 50%. 

 

Restoring the old DB backup with phpmyadmin will bring the store back and all products can bee seen again.

 

 

I have realized that the table "ps_specific_price" is growing very much. I have at the moment a 20% discount on a lot of products with the catalog price rule. And some of the products I'm adding belong to these catalogs

 

I have currently about 1400 products in the shop.

 

 

Does anyone have an idea what is causing this issue? 

 

Thanks 

Tony

considering that PHP 5.5.22 was released on Feb 20, 2015.  So you may have had your store for 2 years, but not using this software.  So the question really is, when did you upgrade the software on your server?  And did these problems start when you did that?  My experience will tell me the answer is yes.

Hi 

 

Thanks for prompt response. 

 

You might be right. However first time I realized this issue was FEB 10th 2015 . The hosting provider is upgrading the PHP versions automatically without notification.

 

Are you saying Prestashop 1.5.4.1 has an issue with PHP 5.5.X in general or only with 5.5.22?

 

Should I better run in with php  5.4.38, which is also provided by the hosting provider?

 

Or als another option should I start planning to upgrade  the prestashop to 1.6.0.14 with one click? Will the shop still work?

 

Thanks

It's quite possible that PS v1.5.4.1 has problems with this PHP version, since this PS version was released before that PHP version.

 

I just tested PS v1.6.0.14 with PHP v5.5.12 and things appear to be working properly, so I imagine 5.5.22 would as well.

 

I would try using PHP v5.4.38 first, I think you might encounter a search issue with PHP v5.4, (search the forums about that issue).  But if that doesn't work and you are into upgrading Prestashop, then you might have no other choice.
