This is not a fatal issue as I’ve figured out a workaround, below . . .
Revo 2.0.8-pl advanced, Liquid web dedicated linux server
downloaded the latest after some issues with the Feb. 23 version of 2.0.8 (my pkg downloaded 03/04/11)
Default provider in Package Manager: modxcms.com ->
http://rest.modxcms.com/extras/
Add Package, select modxcms.com, on the Select Packages screen when you open any of the dropdowns you get "An error occurred connecting to the provider:Modx received a blank response from the provider." etc.
The workaround is that the search still works and while I can find packages I’m familiar with, we can’t browse them.
Edit: Uhh, scratch that, it’s now appearing as a search response as well.
Have several other version modX sites in place on other servers, they are able to connect to the provider fine. Gonna have to go manual at least for today.
