My b2evolution Version: Not Entered

Hi !
Wifey got this today on one of her blogs:

Fatal error: Call to undefined function: preg_match() in /home/username/public_html/conf/_advanced.php on line 117

That's it...nothing else.

We have other blogs working just fine, same server/code (2.4.6).
I've cleared cache.
I've copied over index.php from a going blog, same thing.

Only mitigating factor: we moved webhosts a month ago. But this is a blog that isn't used much, so unsure when it failed.

Googling the error turns up a lot of instances of badly compiled PHP...but the other blogs are working, so that's not it.

Any ideas?

I've found that it has something to do with the domain name handling for that one particular subdomain. If I change the URL handling to be anything OTHER THAN subdomain or absolute, then we can get the site. It must be to do with the mod_rewrite function I am guessing...the new host we are on uses LiteSpeed webserver instead of Apache. It's faster, but we seem to have a few weird issues cropping up.

I still cannot understand how other blogs, that were configured absolutely identically apart from the name, never had any issue.

On a hunch, I removed the htaccess file for this particular blog/subdomain...and it fixed it. So something in the Litespeed Server isn't 100% happy with the htaccess that used to work with Apache. Good grief. :roll:
