Subject: [PATCH 1/3] fix: api version detection in UpdateFlashBackup.php
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

plugin/source/dynamix.unraid.net/usr/local/emhttp/plugins/dynamix.my.servers/include/UpdateFlashBackup.php:415 still reads the API version from _var($mystatus,'version'), but commit 441e1805c removed the code that populates $mystatus (the parse of /var/local/emhttp/myservers.cfg). As a result $mystatus is undefined, so we now send api_version= to https://keys.lime-technology.com/backup/flash/activate. The PHP runtime also emits “Undefined variable: mystatus” / “Trying to access array offset on value of type null” notices before headers are written. Those notices corrupt the JSON response, the keyserver rejects the request because the api_version is missing, and the flash backup state file is never updated—so the web GUI stays stuck at “Loading”.

Because the status request always invokes UpdateFlashBackup.php, every page load trips the same failure path, leaving /var/local/emhttp/flashbackup.ini with loading=Loading. The frontend only listens for /sub/flashbackup events, so until that INI file is rewritten the spinner never clears and the enable button never becomes active.
