So I did some further digging after I also tried a manual install of the latest Concrete5 (18.104.22.168)
from their website, and also encountered this hanging scenario when attempting to manually install it.
It seems that the Supports concrete5 request URLs
and Cookies Enabled
checks both hang with the little loading icons just continuing to display.
This seems to be happening due to a ModSecurity error on the server getting triggered when the install process attempts to access the concrete/js/jquery.cookie.js
It turns out that a lot of people experience this issue, and the easiest solution I've seen that I've confirmed fixes it, is just directly access the setup part of the install and skip the check screen with the following URL format:
The ModSecurity error appears to keep happening, but it doesn't stop you from finishing the install process. Another alternative would be to disable ModSecurity with the cPanel Modsec Manager
, and then install Concrete5, but we would highly discourage leaving ModSecurity fully disabled as it can help protect your website against a lot of common threats.
Aside from that it sounds like the Softaculous
install still works without any issues, and appears to be the exact same version as a manual install so I would recommend using that if you keep encountering problems.
