I would have done this, but the site is only running on localhost on my Laptop. It is not yet online. I am working for a museum, and I would need our administrator for further steps … if you can’t help in this case, I understand. Then I will conctact you at a later stage, maybe. However, Thank you!
Yes, I did. And I did it once again now. I am not sure if I am mentally blocked, but I didn’t find anything on my issue. I disabled all other plugins, played around with image formates, visited the wordpress forum…
Maybe it is a problem with my configuration, I just don’t know.
