Thread:Project:Support desk/Unable to install on VPS - compilation failed and catchable fatal error/reply (2)

You always get the error


 * Warning: preg_match: Compilation failed: unknown option bit(s) set at offset 0 in mediawiki-1.21.1/includes/PathRouter.php on line 120

(in several files at several lines, but always the same error.)

I would say this is a problem with the PCRE library in PHP. recompiling PHP might help without telling it to use special settings for PCRE. With the default it should work...
