Hmm, I have removed (accidentally) and reinstated (eventually) my modxcms.com provider, now I don’t get any packages in the package browser at all, and I get a dialog box that says "Error: error".
If I tried to upgrade one of my already installed packages, I get a dialog that says "provider_err_nf", which I’m guessing is "not found".
I think I’ve screwed my provider set up: currently I have just the one entry with name=modxcms.com and service_url=
http://rest.modxcms.com/extras/ does that look right?
Additional: ah, I think I’ve fixed my provider problems; the new provider had an id of 3 in the modx_transport_providers table, but the entries in modx_transport_packages were expecting provider=1. I can upgrade and browse packages again, but quip is still absent.
If I search for "quip" and watch the traffic, I see a POST request to packages-rest.php with params query=quip&tag=&action=getList&provider=1, to which the response is ({"total":"0","results":[]}).
