Hi all,
I have installed Prestashop 8.0.4 and I have several errors in the backoffice 
I saw already a few posts regarding slow, but I have more than that.
When I try to create a new product (I have around 40 right now), it stays for a looong time until it jumps to the front-office to a unknow page (page no found error).
The ajax request it stays like this:
Also updating products it's a nightmare
I get errors but most of the time it saves the changes ... but really slow. Tem cache, memory, database looks good but the ajax requests not.
I have turned on the cache, compilation, etc and updated all the variables in the PHP according with the recomendations I have found.
Not always but sometimes a simple refresh it takes minutes, even in the front-office.
This is the configuration I have:
Any hint? I really need to fix this
Thank you
Jorge
