Where is the sitemap file located so I can upload it to google?
Yours is installed at:
https://www.outdoorking-forum.com.au/forum/ubb.sitemap.phpWARNING: Your PHP max_input_vars setting is set to a low value. Your current setting is 1000; the default setting is 1000. Based on your current number of forums, a minimum setting of 4350 is recommended. Your forum may have issues such as a blank configuration file, missing settings, or unexpected script behavior if you continue. Please see the "Issues with the PHP 'max_input_vars' Setting" entry on the UBB.Wiki for more information.
This is an issue with your web host and has nothing to do with the Sitemap, the Sitemap creates an index file of all of your forums and categories, whereas max_input_vars is a setting in your webserver configuration (php.ini) which needs adjusted by someone with appropriate permissions on your server.
