I built a new site in Joomla 3.4.5 with JCE editor 2.5.11. When I tried to upload an image in the JCE's image dialog, it failed with
"Upload Failed: No Data". Unlike this case, this error occurs for every image, not just some. I checked in the source code (row 823) that JCE thinks the image file is empty, so it probably fails before reaching the JCE file check.
So I tried to upload the image in backend (media manager). In complains about files being too big instead. The limit is set to 10MB and I tested this with image files of several tens or hundreds kB, so there must be some bug. But how to correct/ workaround it?
EDIT: after upgrade to Joomla 3.4.8 and JCE to 2.5.14, the error message in the frontend changed to
[object Object]. The error in the backend is still the same.
