I realize that the biggest change that probably is causing all this problems with the “extensions” because that it what you comment out, and also gives the installation issues is that compared to the April release, extensions can only be installed when having generated carte number for the website. I understand that there may be god reasons to start “locking” extensions to websites, but there is some privacy creep here as one now requires to expose the installation to the software developer who also thus link website with user. It would be useful to get some more insight from core developer why this change happened but more importantly to fix the installation process. I tried to update 2 old sites but because of carte messed completely up. So even though we can try to get a fresh install working, I have failed to get success with accessing the admin part. The front-end shows but that’s it.
