Tinymce editor blank pop screen problem
As you can see from my portfolio section I am designing and developing the brand new website for The Wallis Arms Hotel in Millstreet, Cork. Im using the Modx content management system for this website which uses the pretty standard Tinymce editor in the backend to allow clients to edit the content on their website.
This was working perfectly for me up until recently when I noticed an annoying problem. When I clicked on the html edit button or the image upload button I got a blank popup screen instead of the usual edit screen or image upload screen (see below).

Anyway, after much frustrating Google searching I came across a solution. The problem occurred because I had changed my site url from wallisarms.com to www.wallisarms.com (added the www) but my .htaccess file still read the site as wallisarms.com. Simply changing this to the latter (with the www) solved my problem.
If after you change the htaccess file the problem remains, try manually typing in the www before your site url and you log in again. Hope that helps someone!
