Hi
I am trying to upgrade an online store using the 1 Click Upgrade module. When I try to upgrade I have an Ajax error in the console that I do not have rights to the ajax-upgradetab.php file.
403
Forbidden
Access to this resource on the server is denied!
The file has 777 rights on the server. I also cleaned the ps_acces table and uploaded the content of pure Presta, but it also did not help.
Can someone please help me?
Prestashop version 1.7.5.2
PHP version 7.1 (also tested on 7.2)
