XHTML validation

Question marks in the title of posts will not validate.

I get thie following error for them:

non SGML character number 133

Unsure of why this is. I've tried validating other forums and they appear to work ok with "?" in their titles.

Any ideas?

Thanks!

Hello Alan,

does it work correctly with vBSEO disabled?

I do not know, will have to verify that.

After testing: Yes, the issue happens without vBSEO active.

Another forum on same host does not have this issue.

After testing: Yes, the issue happens without vBSEO active.

So it must be your custom template issue, not related to vBSEO?

Hrmm...

Issue reamins in standard template.

If I view source and paste it in by direct input - it works fine.
But, if I go by URL it fails.

I've created a troubleshooting thead over at vBulletin® - Instant Community

Any ideas would still be much appreciated.

Thanks!!

The problem is related to a non-standard character in one of your thread titles:
