User blog:Pepman/Aborted by an Extension Hook

Hi there! I've been having an issue with trying to edit pages. Whenever I'm done with my changes, and click Publish, it loads for a second, then gives a notification similar to "The action was aborted by an extension hook." I'm not sure what's going on, but there's a page in urgent need of fixing, and I saved all the changes i made into a text file so I could re-fix it later. Any advice is appreciated!
