Hello - I'm getting this error when trying to use the Media Manager:

Invalid backend response.
Data is not JSON.
The most recent request was denied because it had an invalid security token. Please refresh the page and try again.

I'm running the most recent Joomla & K2 versions and have tried disabling error reporting but still get the message.
Any other recommendations would be appreciated!

If some system plugin is not throwing a PHP warning in raw Joomla outputs (which K2 uses for outputting JSON), try updating to K2 v2.10 (dev) from: github.com/getk2/k2/archive/master.zip

In any case, open your browser's dev tools console and check the errors displayed...

If you use & love K2, please take a moment to add your review and rate it
at the Joomla Extensions Directory: extensions.joomla.org/extension/k2/
