I get a random 'This page is currently offline. We are very sorry for the inconvenience and will fix it as soon as possible.' error

The CMS Questions
1

it is random and doesn’t happen all the time…
so it is hard to figure out the bug.

I’ve put on debugging but I don’t get any errors mentioned…
Using the zero one theme (from January) and 8.3 php

2

What is your server environment?

Also check `phpinfo` via web request, and `which php` on the CLI.

3

Linux com-linweb1017
PHP Version 8.3.30

4

So the CLI and the web use the same PHP version?

No load-balancing, no docker environment, no OPcode cache?

Actually I just build online as this is a Zero One theme: I installed it online (test server, temporary url). And started building and configuring in their settings.
The only issue I can imagine is maybe something with language-settings.
The thing is: we randomly get the error, most of the time the website is just working… But sometimes on load the error appears. And on reload the error is gone again.
Debugging is not showing anything… (If debug is on it should just show the error instead of the debug message, right?)

What you could try is to add some error logging statements in fatal.php temporarily. Or maybe contact the zero one theme developer, maybe they have an idea. The theme is not publicly accessible.
