I copied the folder from another website were I use the plugin and it started showing the image from that other website but after updating the image map item on this website it started working and I have checked that I can create new items. The plugin probably wasn’t able to create the folder because of permissions or other reason. Anyways, thank you!
Update: Now I see that I am unable to make posts full-with, without the sidebar/widget-area…
So… maybe, since I don’t really need the sidebar and have been creating customized ones with PageBuilder, I will just shut down the sidebar completely…
