Eliminate "No extensions available for this version of CiviCRM"
This error is a possible outcome of the "checkExtensions" system check. I propose we eliminate it:
- There's never going to be another version of CiviCRM that has no extensions available, so the message is wrong.
- The error pretty much exclusively happens when there's an error on the c.o side, like an outage.
- There are no actionable steps for someone receiving this message.
- My personal gripe: When c.o goes down, I get this message from a gazillion sites at once.
While I'm aware it's theoretically possible that someone could define an alternate extension directory source from c.o, to my knowledge that a) has never been done, b) if you do that, you shouldn't need a warning in the UI to tell you no extensions are available.
Happy to take this on if folks approve.
