Recently I encountered a strange problem: anybody who links the forum home on Facebook, gets the site's background as the FB image. Threads shared are ok, only the hompage has this problem. The background which is taken by Facebook is indeed preloaded first in page, but I tried changing it, deleting..with no success. I've also tried to add FB's meta in page_container...no luck.
I have no idea what to try
forum is: www.tesoelite.com/forums/
Thanks in advance
