Ok.. Now I'm a Silver member.
I installed the plugin.
Now when I try to insert an event from the front-end I find the menu "upload image" and I am able to upload.
I save the events and I receive the message that the event must be approved..
So, when I go to the back-end to approve the event I don't find the image that I have uploaded befaore and also in the event detail in the site.. What is wrong?
