PhpBB3 BBCodes

My problem is that my BBCode buttons stoped to work. Everything was working fine. And yesterday i tryed to insert a picture on a post. Whwn i cliced on [img] button and nothing happened.

It would be great if someone can help me.


P.S.:
How did you to have de scrolldown bbcodes?

First you need to make sure that your style is the same version as your phpBB version.
Also think about what you have done, modding and so on before the error occured.
