weird problem with image tags in sig
 

So when my users try to add bbcode for image in their sig and then submit the changes, the site takes them to a blank white page.

I just tried to do the same thing and I come up with this error.

PHP has encountered an Access Violation at 01B9937E

I presume you are using IIS. PHP is not terribly stable under IIS. I recommend you switch to Apache instead.

I've been running PHP under IIS for over 3 years with no issues. I don't think it's that. I have 3 other vbulletin sites running on this same IIS/PHP installation, and they don't have the issue.

I think the error code i got was a fluke issue, as I have not been able to reporduce it, but I can reproduce the "blank white screen" when trying to put an img in the sig with the img tags, as long as you use the "upload a sig pic" feature in the signature editor there isn't a problem.

Okay. I thought you meant the access violation was consistent.

The blank page happens when a PHP error occurs while output buffering is on. This happens in a lot of places within vBulletin (and depends a little on your PHP configuration).

The error should be in the web server error log. By default under IIS this is in C:\WINDOWS\System32\LogFiles.

found it.. I had a plugin from my pre 3.7 upgrade that was screwing it up.. extended signature limits, guess it's not compatible with 3.7 :)
