Do you have /web in the url you use to access the CMS?

Yes i have! https://digitalmidia.dgvisual.com.br/library/view -

Please use this link : https://xibo.org.uk/docs/setup/prepare-your-environment to set up your CMS correctly, it’s also more secure this way.

I had the same problem and there was no way to solve it and I have version 2.3.4
