User blog:PowerCrusher04/Extension Hook

Hello everyone, and welcome to my first blog post.

This isn't going to be long since I only want to know one thing right now: Whenever I try to edit specific pages, like levels in Slushie Studio, it doesn't allow me to do so. No, it's not something only admins can do. Anyone can fill in the "Blockers" or "Other" section  of the "Infobox level" template (I think that's what it's called). Anyways, I try to do just that, but it doesn't allow me in specific levels. It says: " The modification you tried to make was aborted by an extension hook".

Can anyone answer these questions?:

1. What is an extension hook?

2. Why doesn't it allow me to edit in specific levels? Am I doing something wrong?

In advance, thank you for answering!
