Myself and a colleague of mine have updated to ver 2.3 of silverstripe (over top 2.2) which was successful. When I go to add a link to some content and click on the "link" button in tinymce it works for me, however when my colleague does this same process he gets a insert link error. The errors are shown here that he receives. I dont know why only he is getting these errors, and want to know how to resolve for his side. Any help appreciated!
