Hi K2 Team,

It's been since 3 day i'm block with K2 Media Manager !!! Unable to access the tool :(
I got : "Error: Invalid backend response.Data is empty." popup. the same error appears in back end (k2 media manager). there is no error in Joomla media manager, only K2.

Please find the screen shot of the error attached !

Please help I did review all topic about this issue but didn't find a PROPER resolution one !

My website was hosted via: Localhost (localy), When I did transfer the website into my web host I not working any more!

Do I have to add something on my webhosting via FTP ?

Thanks,

Resolution: (it worked for me)

Go to file: "elFinderVolumeDriver.class.php"

File Directory: on local host or web hosting search:

/administrator/components/com_k2/lib/elfinder

File: "elFinderVolumeDriver.class.php"

Open the file with an editor:

Go to line 747 where the line "$this->_checkArchivers();" should be! And disable this line by adding double slashes "//" (Example: //$this->_checkArchivers();)

Hope that help!

THANKS GOD! IT FINALLY WORKED FOR ME! :)

Thank you that work for me to.

work! thks.

I have the same problem but the solution mentioned above did not help.

Also disabling error reporting did not help.

For me the strange thing is that the problem seems to be kind of slowly progressing. At first only I had the problem on my computer, then a few days later somebody else started having the problem but at first switching to another browser helped and then it stopped working there as well.

Which version of Joomla! and K2 are you using?
Also in the network tab of your browser's developer tools can you check for the response of the XHR request?

This screenshot will help you.

Joomla 3.6.2
