So my guess is something in PHP changed, probably a regular expression -like function? On the Wordpress support forum I posted the following, inclusing a test environment: /* 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: ~ http://www.vevida.to/php/php520/phpinfo.php ~ http://www.vevida.to/php/php521/phpinfo.php and both Wordpress installations can are located here: ~ http://www.vevida.to/php/php520/index.php ~ http://www.vevida.to/php/php521/index.php As you can see, a permalink like ~ http://www.vevida.to/php/php520/index.php/2007/02/21/lorem-ipsum/ works, and ~ http://www.vevida.to/php/php521/index.php/2007/02/21/lorem-ipsum/ does not. [...] 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? [snipped something about mod_rewrite and ISAPI_Rewrite] */ (http://wordpress.org/support/topic/107133) Looking at this in the test environment, my only conclusion is that something within PHP, or in the pcre functions, has changed. - -- Met vriendelijke groet / Best regards, Jan Reilink VEVIDA Services bv, janreilink@vevida.com Postbus 329, 9700 AH GRONINGEN, +31(0)50 - 5492234 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) iD8DBQFF3VWVzmimqimD3mIRAnCYAKCmCgd/zw6d3qgoztsdYGKgvC5AuwCeJMWc eE4HRDKz2lVZCZ2aS55xNxQ= =VM5o -----END PGP SIGNATURE-----
