Wordpress - adding new -> Loading, please wait...
I have installed H5P on my Wordpress site. I was able to get new content types. However, when I want to use them, the message: Loading, please wait... appears. It doesn't disappear and I am unable to continue doing anything. It is a fresh Wordpress site so there are no other plugins installed and I am hosting my site on one.com. I have tried it in different browsers and the problem remains.
Can you help me?
Thanks a lot,
