Thread:Project:Support desk/My site is messed up somehow/reply

Hi!

You are using MediaWiki 1.19.3 and the site displays this error:

Warning: preg_match: Compilation failed: group name must start with a non-digit at offset 8 in includes/MagicWord.php on line 872.

This sounds like a duplicate of this problem: Thread:Project:Support_desk/Warning:_preg_replace:_Compilation_failed:_group_name_must_start_with_a_non-digit_at_offset_4_i

Result there was: This error happens because the server where your MediaWiki is running upgraded the PCRE package to a newer version, introducing this breaking change. Please, upgrade MediaWiki to solve the issue (latest releases of MediaWiki 1.19 and newer versions have fixed this issue).

See Upgrade for our upgrade guide!
