After looking further into the problem, it turned out to be an issue with wordpress. Everything is working great now.
Sorry it took me some time to get the information for you. See below.
yes, you have admin rights.
We had to wipe the whole WordPress site and start over. It seems to have several errors going on, so we started fresh. Unfortunately, it did not solve the problem of inserting new images in the layerslider. We tested the plugins and there does not seem to be a conflict.
Everything appears to be updated.
