Wordpress Database and Header Errors After Posting a Comment and its Solution

WordPress Database and Header Errors After Posting a Comment and its Solution

Posted on November 20, 2010, filed in: Monetizing

Today i realized that this website was giving a nasty WordPress Database Query and Cannot Modify Header errors after posting a comment and i am wondering since how long these errors have been there.

All the files involved in the error were wp-comment-post.php, wp-db.php and pluggable.php.

After an intense tiresome search on internet i came across so many different kinds of errors related to wordpress comment and database and each issue had its own fixes. But i tried to follow one of the methods that was followed to fix each kind of issue and that was to check if any comment altering plugin was causing the problem or not.

There were two comment related plugins that i was using on this website. One was Brian’s Threaded Comment and the other one is Comment Luv.

Comment Luv simply fetches the latest post from commentators URL and displays it along with their comment.

Brian’s Threaded Comment highly alters the comment section, it lets commentators reply to earlier comments making it easier for readers to check replies to respective comment.

I simply deactivated each comment while checking if posting comments were giving errors or not and found out that Brian’s Threaded Comment was giving an error on this website.

So many bloggers are using Brian’s Threaded Comment and i don’t understand why it was not working on this website. Compatibility issue seems very unlikely but it is very much likely to be an error related to the theme. But again theme developers are clueless about the error and this is the updated version of the theme. But whatsoever, since i got rid of the Brian’s Threader Comment plugin, everything is working just fine and posting comments are no longer showing those nasty errors.

Solution: Try deactivating any comment related plugins that you might be using and see if that solves the problem or not.

Here are some other possible errors that you might be facing..
