Community Tip - You can change your system assigned username to something more personal in your community settings. X
Error occurs when user opens a specific file and also when user tries to insert a tag.
User presses Enter and the list of available tags appears for less than a second, disappears and then the error appears. Work-around for user is to use the command line or “Insert Markup” from the menu.
Is there a way to increase the area within the element?
