Do you have VBSEO installed?

No, just the sitemap generator.

I don't suppose you have a test site with the same issue?

IM having a problem with the shortened url definition where what happens is, it cuts off everything below the last post. The quick reply box, footer, everything.

Which shorted url definition are you using?

No I don't, I could have a whack at trying to set one up, probably a good idea anyway. :p

doesnt work for me(

can u tell me from this mod how can i allow embeded code in a specific section of my forum..?

When I first installed this hack everything worked perfectly. YouTube must have changed something since the, because the only way I can get anything to embed is by enclosing the ending code of the url in youtube tags, as such [YOUTUBE]5mV_HHL-h6g[/YOUTUBE].

Also the sig embedding displays at full size no matter what numbers i put in.

I have installed the latest upgrade and definitions as per instructions to the best of my knowledge, but to no avail. I have not read every single post in this thread as 100+ pages is just too much. Any suggestions as to what I might be doing wrong? Forgive me if I'm asking a stupid question.

Here's a link to an example of how it behaves.

YouTube changed their "share" URLs recently and an official definition update hasn't been released yet. I believe a couple of options were posted earlier (recently) in this thread- either try an unofficial definition or copy a youtube url from the browser address bar, note a share url.

Looking at your link the first video you posted shows the YouTube video icon next to it, so it did attempt to embed but for some reason it believes that video is not allowed to be embedded. What code do you have in your AME Definition in your Validation box? Consider removing it and trying again.
