Hello
I have a big problem started after I exported the database. After which I wanted to do a presta upgrade, I entered the cache, turned it off, and after refreshing the white page. The store is working and the admin panel shows a white page, when I turn on debug mode _PS_MODE_DEV_ to true then admin works normally but in the store only the main page works and vice versa.
I don't know what might be wrong.
