[I hope “How-To and Trobleshooting is the correct forum for this…]
Last week we, the hosting company I work for, upgraded from PHP version 5.2.0 to 5.2.1. And suddenly customers started complaining about permalinks stopped working and returning 404 errors. I am now trying to find the cause (probably changes in some of PHPs regular expression-like functions), but my guess is the WordPress developers here know more about the rewriting code of WordPress than I do to pinpoint it 🙂
For my test purposes I have created two identical application folders with one difference: One of them uses PHP 5.2.0 and the other 5.2.1. They both use the same php.ini file. The phpinfo() information is located here:

We noticed the same behaviour with blogs/cms’s like ExpressionEngine, which we could “fix” with ISAPI_Rewrite. But I have not tested that thoroughly…
Is this a problem I (or better, the WordPress developers ;)) can fix by changing some code or functions? Or is this a problem with (some of) the PHP core fuctions which needs to be fixed by the PHP developers?
If anyone is capable of rewriting the .htaccess rewrite rules to ISAPI_Rewrite (http://www.isapirewrite.com), I would be more than happy to test them 🙂 ISAPI_Rewrite support within WordPress (next to .htaccess) would be a nice addition, for websites hosted on Windows/IIS.
Thank you in advance for any insights, pointers and/or help.
