Since I updated the JCE editor to the 2.5.16 version I've been unable to upload files via the File Browser. It always popup an alert window displaying:
The server returned an invalid JSON response
If I look into the JSON response from the developer tools I find a valid JSON string but with some html at the end that must be messing with the JSON parsing.
<\/a><\/span><\/div><\/li><\/ul><\/li><\/ul>"}<!-- l: nobody -->
I tried from different browsers, users, reinstalling the Extension, updating it to 2.5.17 and later to 2.5.18 and the issue remains.
I'm actually using the Joomla version 3.5.1
Has anyone faced this or knows what to do?
Thanks
