I migrated the entire site to another development server (different hosting company) and the plugin works fine. I contacted the hosting company for the production server (flywheel) and they responded:

“I watched the error logs when trying to upload the files and nothing is being thrown at the server level. I don’t think this is a server related issue as much as a problem with the plugin and they way it is trying to communicate with our server, but unfortunately I don’t have any logs from the plugin to look at and that would need to be something the plugin developer should look at since we wouldn’t be familiar with their code.”

If I rename or remove the file extension on the .jpg or .png files, they will upload with no problem. Of course I don’t wish to do that.

Any further ideas?

I am running Safari 9.0.3

The hosting company (Flywheel) says the server is running PHP 5.5 with the GD and Imagick module enabled. They say they are happy to help with any troubleshooting steps as necessary.

And yes, I did try Chrome version 49.0.2623.112 with the same result.

I did turn on WP_Debug mode and noticed that when I attempted to upload a jpg or png, the error message changed to “not json”, when I turned off WP_Debug, the message returned to “Data is empty”.

If it will be of any help I can email the server log files.

In Safari console:

elfinder debug: [error] [file-manager-wrapper] – “Invalid backend response.
Data is empty.” (elfinder.full.js, line 4676)

The jpg file I tried was 149kb and the png is 454kb

ok, it appears the problem is limited to .jpg and .png files.

.zip, .txt,.pdf, and .docx files are ok.

Hello Aftabul,

Any thoughts on the “Invalid backend response ??? empty” error when trying to upload files?
