It says something like page not found. I did change the url to community/ from forum/, but had problems getting the /community/ to stick.
The url was to a community/ url, but I just changed it to /forum/ again and restarted the server and am testing. I have a VPS, and have the option to do a graceful restart and forceful restart. I just did a forceful restart.... Hoping this will fix it.
Just wondering about something here? Have you by chance edited the .htaccess file and removed the "#" from "#RewriteBase /xenforo" to use it. Also, were is your .htaccess file located? In the Root (public_html), or in your forums folder with the rest of the files (were it should be)?
