Hi andrewjs18,
you’re friendly URLs ... did you rename ht.access to .htaccess? (or disable the friendly URLs feature first to check if that’s causing your errors)
Options +FollowSymlinks RewriteEngine On RewriteBase /cms
check that part of your .htaccess file:
Options +FollowSymlinks RewriteEngine On RewriteBase /cms
(adding your subfolder "cms")
your server got mod_rewrite feature?
*clear your MODx- and Browser cache*
