Troubleshooting

Description	Affected Installations	How to Fix
Update notifications do not work	Installed at 1.6.1 or earlier and updated to a version in 1.6.5 - 2.0 Installed at 2.0 - 2.1 without "Enable Software Update Notifications" in the install process Installed on any server where the PHP option fopen_allow_url is disabled	Enable fopen_allow_url in the hosting environment (updates themselves won't work without this option; it's the crux of the remote update process) Set value of the column `unique_id` in table `x2_admin` to a string other than "none" or null, i.e. UPDATE `x2_admin` SET `unique_id`='[something]'
