Auto Upgrade from 1.5.3.1 to 1.5.4.1 issue with class_index.php

[RCP90]

Hello,

 

I used the 1 click update module to upgrade from 1.5.3.1 to 1.5.4.1. The upgrade seemed to work fine.

 

Once I tried to access the website or back office i received the error below.

 

 

/public_html/cache/class_index.php is corrupted. Please remove this file, a new one will be regenerated automatically

 

 

I tried deleting the file as suggested but still received the same error. The only thing I could do to get things working again was to copy the same file from a back up (1.5.3.1) to the upgraded directory.

 

Now I know this is probably the wrong thing to do, but it did seem to make the website work again, and also the back office is working perfectly.

 

I know some others have had this issue, but no one seems to have figured out a correct fix. could the method I used potentially cause any future problems? I am only testing PrestaShop at the moment.
