Just have this little niggle that I can not work out and cannot find via search.
When I tested registration and click terms link at registration prior to clicking the registration button, it takes me to /forums/help/terms which has this on the page.
I have cookies accepted, never had a problem. I checked my redirect in cPanel, no problem there.
I cannot find help directory in my root directory so maybe that is it? I extracted the XenForo file to have a look in and there was no help directory in there as well so it apparently is normal.
You can also see that there is no error in the server error log.
I have changed domains, so that is the only thing I can think of that could cause the problem. Everything else is 100% perfectly functional.
