"Alerts" page is loading correctly and all the pages I mentioned above was correctly loading a couple of days ago.
I'm using different spaces and in space management all the permission are granted to the spaces I'm experiencing the issue. Meanwhile in "default" space the pages are loading correctly
The behavior in my case is similar to the one in the bug you mentioned but I get always the same message in all pages (the one I posted the screenshot in my first post - "Add a Security Integration").
Permission in the space in which I have the issue are as follow
Apache, Apache Lucene, Apache Hadoop, Hadoop, HDFS and the yellow elephant
