When I went into the settings I did notice there was no list selected or Role to Sync filled in anymore but that is because I just had to turn all plugins off & start re activating. I did not go back in and fill in the fields so it may have something to do with trying to sync without the proper settings put into the fields. (i.e. the list to sync with was empty but it the ENABLED setting was YES.)
Now that I’ve stopped syncing should I try the FORCE SYNCHRONISATION setting (Synchronise All) ??
