Hi, I tried all that and could not get any debug messages out. However, whilst trying to debug why I was not getting debug messages out, I noticed that the the media upload path was an absolute value rather than the default. I changed back to the default and this now works.
Thank you for you help.
Tried those things, including removing the Lite Speed Cache plugin, but the problem still persists. The URL being generated for the CSS is invalid. It’s missing a “/” between the hostname and the rest of the URL.
Also tried switching the form to Ajax loading and enable the disable cache option on the form.
Still no luck.
