getthing the above error whenever I try to "POST" anything on a buddypress site. whatever I'm trying to do actually gets posted once I go back to the page.. but want to fix this error. I found a post talking about "WP XHTML Validator" plugin that's suppose to search your pages and tell you invalid code.. or at least I think that's what it was.. but I couldn't find the plugin.. don't think it's supported anymore as it was an old post over 4 years ago.
is there anything like this now that you would recommend? preferably not a plugin just a program I could have scan a folder of php/html or whatever files.
any help would be appreciated.
