Suddenly. All our tp_classic with Astroid astroid-framework-3.0.11 are hanging when save.
It happens on different sites on different domains.
Joomla 5.0.3
PHP 8.2.16

Astroid Clear Cache has no improvement.
Also a fresh  astroid-framework-3.0.11 has no improvement.
Do you have a solution for this?
We have different websites with  tp_classic.

Did the problem suddenly appear or did you change anything? 
In Joomla or perhaps with the provider?

Was there also an attempt to save from another PC (i.e. from another DSL connection)?

Hi Dirk,

I see now that on the same provider another
 tp_classic with Astroid astroid-framework-3.0.11
is saving fine.
It seems a conflict somewhere?
Hope there is a solution somewhere probably in the astroid-framework?
Regards,
Milian

If necessary, fill the entry live-site or something similar in the configuration.php? 
In most cases it should be empty (=two quotes).

And while you're about to edit the configuration.php, so$live_site=''; then check all the other entries again, such as the paths to the tmp and logs directories, etc. 
And to be on the safe side, check the .htaccess again.
