Thread:Project:Support desk/Fatal error: Class 'LinksUpdate' not found/reply

Generally this means that your install somehow got corrupted or you are missing a file.

Check to make sure that the file /web/htdocs/www.ivys.it/home/wiki/includes/LinksUpdate.php exists, and actually has stuff in it.

You could perhaps try re-downloading the tar bar and re-installing.

This type of error (beside the whole fatal error bit) will probably make categories, special:whatlinkshere type features not work.
