We have several v5.4 sites and as per the title of this thread, when we try inline editing the error in the console is "Uncaught RangeError: Maximum call stack size exceeded" and nothing can be edited.
This was raised by someone else over 18 months ago, but no one replied with a fix. That post is here - http://www.sitefinity.com/developer-network/forums/developing-with-sitefinity-/clicking-edit-button-on-front-end-throws-error-uncaught-rangeerror-maximum-call-stack-size-exceeded-
The images attached to that post are exactly what we're getting. Any ideas what could be causing this?
