It could possibly - I've had two hacks that both use global_start conflict with each other, depending on its contents. To test this out, if sort your plugins by hook location and find others that share global_start. Then try disabling others one at a time to see if there is a conflict.

Also, although Dreamweaver may be satisfied that all tags have ends, your total script may not start/end. When a page is displayed, it displays everything in that page inclusive of all templates. If one previous template has an unclosed tag, or one latter template does not close, then you might have issues. The same goes with the basics of html. What you see in Dreamweaver is only one section of code, which satisfies by closing all tags, as you state. That is just something to keep in mind. (I've run into this upon occasion when building non-vbulletin websites completely from scratch)

Also, keep in mind, that although the code may satisfy tag closure, the code itself may have an issue within itself or with something else it is being used with.

If you want, PM me the code or paste it here and I will try to look at it later.
