I am not able to insert an image - Joomla 3.8.7 unite_slider5.0.14 the images you see here are loaded via the enter image url for slide background so I could show something to the client.
Please provide URL to your site and super admin login details so we can take a look and see what could be the issue
your system plugin "Rapi Admin UI" is guilty for this issue. Disable "Transition Effect Between Pages" parameter in that plugin and everything will work as expected
Thank you so much ! works like a charm now ;)
no problem at all. Glad I could help
