While trying to click an action button on a request on the front end, the page does not refresh and "error on page" is listed at the bottom left of the browser window. We are not able to move or save requests.
Katy - if you're on 7.5 or later then you also have the option to configure rules to fire on page load (and other options). If you're running 6.0 or 7.1 then you only have the "apply on creation" or "apply on field change" options.
Since this does sound like a rule issue, have you tried Mahendran's advice above?
