I tried to put tags on my pages, and this is what I got on one of my pages..I tried to put it back but it wouldnt work when I did the restore method..my site is http://www.onlinepsychicadvisors.com, it is just my about us page, this is what I get when I am trying to edit it..even tho, on the edit page, it all looks fine..when it says view page, I see this.Warning: include(/home/onlineps/public_html//wp-content/plugins/content-gallery/gallery.php) [function.include]: failed to open stream: No such file or directory in /home/onlineps/public_html/wp-content/themes/psychic_advisors/home.php on line 13
