Hello,
since my hosting site is disabling PHP 7.3, I had to upgrade prestashop to newer version.
I have followed the steps to upgrade manually.
Now when I want to create, or modify an existing product I can't see the description, or resume textboxes / text.
As so I can't input any text.
On the website itself the 'old' existing products still show the descprition and resumees...
I searched a little bit on the forum, but can't find anything useful for this. Tried deleting the cache: no help.
