Hello Toufiq,
Thank you for taking care of this issue. I have been able to replicate this (renaming template overrides for addon "Image") for several other sites and this has solved the issue with front end editing.
If anybody cares to know, following these steps with the template override for the "Feature" addon for the Revibe template solved a very similar problem when trying to edit in the front end. While the "Image" addon override is no longer included with the latest version of the Revibe template, the troublesome "Feature" addon override is. This process of renaming the "Feature" override each time the template is updated will be required.
Toufiq, could the "Feature" template override simply be removed from future Revibe templates? I did not notice any change in my Feature addons when I renamed the template override. Thanks!
