2 of my sites on one.com are no longer working.
I'm getting: "Failed to load resource: the server responded with a status of 503 ()".
Both have version 1.20.0 (latest version, updated in Aug 2021 and it was running fine since then) and the backend is set to use PHP 7.4.
Also PHP error messages are set to "on", but I'm not getting any additional error messages.
I've involved support of one.com and they're currently looking into it.
I was wondering if anyone else is also experiencing issues on one.com?
Or if someone has a clue about the root cause (my local copy of the website is running fine on my pc)...
