Hi @aces thank you for your input, I am using private buddypress that was refered to in thread you mentioned but deactivating all plugins except buddypress did not change anything. I have set up a fresh new buddy press installation to check if it is just my installation, but its the same there I added the code that rodtrent mentioned but that didn’t change anything as well. It looks like it is locked in a redirect loop between e.g. http://example.com/buddypress/groups/group1 and https://example.com/buddypress/groups/group1 because the link that is shown in the url field of the browser is http but all the other pages are properly loaded with https. I have changed the wordpress and site url to https.
