Good afternoon and a happy New Year to you all.
Our problem is this: We can’t get the interoperability protocols to work. The person who supports the web of the magazine cant find the problem. I attach the screenshots where you can see the errors that appear when we do the validation, and also the screenshots in which you see the modules that we currently have installed . Does anyone know what the mistake may be and what is the route is to fix it?
Thank you very much!
