CMS Made Simple Forums

We have a simple site running version 2.2.14 which was working fine until last week. Today when we tried to reach the site we only get the following error:

ERR_TOO_MANY_REDIRECTS

This is running on a Rocky Linux 9 server with PHP 8.1.32 and Mariadb 10.5.27. The site has been running in this server for years (was running on Rocky Linux 8 a year ago and got transferred to 9). The site has not been modified this week, last modification last week was to upload a whatsapp qr for the main page. How can I try to debug the issue? I see no errors on the log files. We can log into the admin console but CSS looks broken.

Is the download site for CMS Made Simple working? I tried to download the latest version and I get an error.

Try commenting out your .htaccess file first, see if that clears up the redirects issue. Also check the browser console for mixed content issues etc., especially in admin. Also make sure you aren't out of disk space or anything. Do each test in a new incognito window after closing any other open ones as browsers can cache redirects.

Our server has had some downtime this week due to issues at our host, but currently seems fine.

There is no .htaccess file in the root directory for the site. This is all I see in the access log file for apache:

Ok, I have found the culprit. Recently we moved our DNS to Cloudflare and last week I decided to try out the Proxy functionality. It seems this interferes with CMS. I have disabled the Proxy though the Cloudflare panel and everything seems to be back to normal.
