I'm getting this error after an auto-upgrade to 3.0.1, with plugin Role-Scoper. Location:
/plugins/role-scoper/lib/agapetry_config_items.php on line 98
function is_member($name) {
return isset($this->members[$name]);
}
So what happened to members[$name] in 3.0.1?
I see various mentions of this error, no real solutions. My approach so far:
1) Need to get control of site: Rename the role-scoper directory to deactivate it.
2) Disable the site by activating Maintenance Mode plugin.
3) Leave role-scoper deactivated but check the activation status and update status of all other plugins.
4) (Later) Diff 3.0 and 3.0.1 to see what happens with members[$name], or wait for someone here with a clue to post some wisdom.
Crud, and I thought I'd get a better release if I just waited a while to install this...
