What's going wrong
Several site owners report that after installing or updating the WordPress Beta Tester plugin, their site stopped working. Some got fatal errors, others saw server timeouts on the plugins page, and one was locked out of the admin area until the plugin was removed by hand over FTP. Others hit fatal errors just from changing a setting. Because the plugin changes core update behaviour, a single failure can take down a live site. Owners who test beta releases want a safer way to run them, with a clear recovery path and a warning before a risky change goes live.
