Hello,
I have a problem saving the setting.
The message appears ...
"Firewall Detected!
Your server returns "Forbidden" when trying to POST X3 settings to x3_settings.php. This indicates that your server has a firewall, which is blocking the POST. You need to ask your host to disable the firewall (or disable some rules) for the /panel/ directory.
There is nothing wrong with having a Firewall, but X3 needs to be able to SAVE settings obviously. The firewall is meant to protect your website, but your X3 panel is already protected by login for known users."
I contacted support and asked for ModSecurity to be changed. It turns out that I can do it myself from my panel after logging into the server. Unfortunately, this does not solve the problem. Still some firewall blocking access to "x3_settings.php"
PS. This link (viewtopic.php?t=9282) explain a lot but not solving my problem.
