Titles in support forum have disappeared

Hi,

My titles in my forum page have disappeared http://www.thesmilingmind.co.uk/the-smiling-mind-forum/ and I can’t get them to appear back again. Also posts keep adding on the page, I have not put in, despite keep deleting them.

Access is granted and any help would be appreciated, please? I am using the upfront editor and spirit theme as well as coursepress, the site, doesn’t seem to be running as fast as it was either.
