Content not saving and Page becoming unresponsive

Hi everyone.

We're having some issues with H5p on our moodle instance. 

When creating content (especially part of the quiz set) it is not saving the work. 

Finally when the work was "created" it created a double of the actvitiy but didn't save the content "Screenshot 1". 

 

I am also getting the "Page Unresponsive error"

 

Please help.
