LibGroupSocket was not updated a longer time and stil uses the embedded LibGPS2.
But LibGPS3 exists meanwhile and should be used (maybe it's not compatible to LibGroupSocket, I don't know).
Try this verison of LibGroupSocket:
https://www.dropbox.com/s/15kje333hj...bStub.zip?dl=0
You will still need LibStub installed for LibGroupSocket
And you need to install the following libs into live/AddOns as standalone installations of the dependencies:
LibAddonMenu
LibMapPing
LibGPS v3
LibStub
Hope it works and fixes your issues.
If not, please write a comment to the LibGroupSocket addon comments or check there if the author already said it will be updated or not.
If no: Remove it and the addons which use it, and install other addons that do similar stuff.
