Is anyone else having problems with it?

I'm receiving this:

A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: https://www.mediawiki.org/wiki/Manua..._update_script
Query: SELECT page_title,old_text,old_flags FROM `crossfire_page`,`crossfire_revision`,`crossfire_t ext` WHERE page_is_redirect = '0' AND page_namespace = '8' AND (page_title NOT LIKE '%/%' ) AND (page_latest=rev_id) AND (rev_text_id=old_id) AND (page_len <= 10000)
Function: MessageCache::loadFromDB(en)-small
Error: 145 Table './wikin/crossfire_text' is marked as crashed and should be repaired (localhost)

/discuss or /help please. I need to upload a couple pages.
