We just had a new customer who moved their wordpress website from another hoster to us. After it was moved we immidiatly upgraded everything to the most recent versions since it was somewhat outdated.
Now we get the messages like :
You don't have permission to access /wp-admin/admin.php on this server.
when we click on the S2member plugin menu entry
The exact link is : /wp-admin/admin.php?page=ws-plugin--s2member-start
We tried everything from putting back the old version.
To adjust permission on all directorys and files.
I even removed the .htaccess files to test if this was a problem but nothing worked.
Does anybody know what can be wrong or how to fix this issue
