Can't edit content after 1.8.2 wordpress version

Just after today's upgrade, it seems that I can't edit the previous content  through Wordpress nor create new one. Just view and execute the previous created content. 

 

The console is showing the following:

JQMIGRATE: Migrate is installed, version 1.4.1

h5peditor.js?ver=1.8.2:115 Ajax request failed

h5peditor.js?ver=1.8.2:116 Object {readyState: 4, getResponseHeader: function, getAllResponseHeaders: function, setRequestHeader: function, overrideMimeType: function…}

h5peditor.js?ver=1.8.2:117 parsererror

h5peditor.js?ver=1.8.2:118 SyntaxError: Unexpected end of JSON input

    at JSON.parse (<anonymous>)

    at parseJSON (jquery.js?ver=1.8.2:2)

    at Fn (jquery.js?ver=1.8.2:4)

    at k (jquery.js?ver=1.8.2:4)

    at XMLHttpRequest.r (jquery.js?ver=1.8.2:4)

I have no idea of what that means or how to solve it. Just using H5P (which is the best tool for Wordpress) to make some exercises for my students using fill in the blanks and a couple more. Thanks a lot in advance. Any help is more than welcome. 

 NEVER MIND: I FIXED IT REINSTALLING THE PLUGIN. Thanks, anyway.

Do you have any idea what might have gone wrong? If you look in your web server's error_log there might be some useful information there.

I'm glad you got it working again, though, you shouldn't run into issues like this while upgrading.

No idea what went wrong, but in anycase it is solved and working like a charm. Thanks a lot for your interest.
