If you or your members are trying to login to your WordPress website/membership and cannot login and get an error like:
Error while checking for update. Can’t reach update server. Message: Couldn’t resolve host ‘leadbrite.appspot.com’
This is due to the Leadpages plugin. We have found that if the Leadpages server goes down and WordPress cannot talk to it, it takes all user logins with it and your users will not be able to login
The only solution while the Leadpages server is down is to disable the Leadpages integration plugin either via FTP (change the folder name of the leeadpages plugin folder) or delete the plugin.
Once this plugin is deactivated, your login ability will be restored.
