Fatal Error In Prestashopcollection.php

[Briljander]

Anyone know what can cause this?

 

I havent really changed any php-code at all but the system engineers at my hosting company helped me upgrade the server with EasyApache 4. It worked as it should at first except that memory limit was to low (only 32MB) and when they later on changed to 128MB this problem appeared. I do think they have moved the .htaccess too but i have tried to put an old copy back but that doesnt help.

 

Fatal error: Class PrestaShopCollectionCore contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Iterator::key) in /public_html/classes/PrestaShopCollection.php on line 726

 

Thanks in advance
