Facing "temporarily unavailable" issue on Backoffice

[d2o]

Hi guys,

Today, I updated a Prestashop installation from 8.2.3 to 9.0.2. Since then, most of the time, when browsing the Backoffice, I will see the following message:

"The page you are looking for is temporarily unavailable. ..."

Until now, I could not figure out anything causing this. In the PHP logs, there are some Deprecated messages, but that's it. Switching the shop to Debug Mode (via SFTP, switching on all debug info) does not help either. 

The Frontoffice is running fine and smooth (currently in Maintenance-Mode). It's only the Backoffice.

Any suggestions on where to look or what to try out are most welcome. I would be very unhappy, if I have to go back to 8.2.3 to have a working shop. Especially, as IONOS will soon start charging for the use of PHP 8.1.

Thanks,
Stefan

Hoster: IONOS
PHP: 8.4
Prestashop: 9.0.2

Hi, try enabling debug mode to see if it shows anything.

2. Don't work with IONOS

Hi,

as mentionend, debug is already active. Except for some deprecation messages, there is nothing to see here.

Ad 2.) Not my choice, I am only maintaining the application. 🤷

Cheers,
Stefan

It would be interesting to see what it shows you in debug mode, but if you say it's not important, I'd say this is a problem with your server. If you can rule it out with another one, try it.

Well, the only failing thing I see are AJAX-calls to https://api.segment.io/v1/i, which are blocked. Not sure, where these come from.

Seems, I need to contact IONOS for this one. And they will say "We don't support custom web-apps". *sigh*

Cheers, Stefan
