Recently, my store began behaving strangely on the backend. The front facing customer experience seems to be unaffected, but when I try to make any changes to products, configurations and more, prestashop saves the changes but shoots me to a completely blank screen with no errors.
I tried turning debug mode on, but there are no errors that display - the screen is entirely blank.
I've tried this across multiple computers and browsers, so that does not seem to be the issue.
Some things do work, such as saving general preferences. But if I attempt to make any changes to a product, category, voucher or almost everything else this blank screen occurs.
edit to add:
My Memory Limit is set to 256M
I've tried to clear the cache both automatically and manually and that did not fix it
The only thing that has changed recently were a bunch of updates for prestashop core modules, but I don't know if the problem was also happening before the updates.
