Answer 1

You are probably using a different Apache version with a different regular expression engine. The Apache versions since 1.3 use POSIX ERE while the versions since 2.0 use PCRE. And only PCRE support the non-capturing group (?:expr).

So try a pattern without them:

RewriteRule ^category/([0-9]+)(/([^/]+)(/([^/]+))?)(/([^/]+)(/([^/]+))?)?/$ ./category.php?pid=$1&catname=$3&page=$5 [L]
