If the output stops in the middle of the source code, there is a server-side error. I suspect it is related to a plugin or theme that is not compatible with PHP 8.0. The exact reason for the error should be visible in the error log. You can find it in your hosting area. If necessary, the support of your hosting can help you.
Alternatively, you could also enable debugging in WordPress. How to do this is described here: https://wordpress.org/support/article/debugging-in-wordpress/ – also here the support of your hosting can help you if necessary to edit the file accordingly.
In both cases you should be able to see what the cause is in the logfile.

HI @threadi
1. The error logfile in my hosting area show no error to this issue. I tested the blog posts of different subdomains from my multisite today at many times but the last error in my hosting error logfile is older than 24 hours and it is non php error.
2. The debugging file in the content area doesn’t work if I change define ( ‘WP_DEBUG_LOG’, false ) to ( ‘WP_DEBUG_LOG’, true ) in the wp-config.php. No error log file written there! I tried the solutions with additional code snippets (https://wordpress.org/support/article/debugging-in-wordpress/) always no error log found there. I don’t know why!
All subdomains work very well including all content in blog posts before php 8.0, but now all post content of all subdomains is missing after title meta, only in the frontend.
I will test the post content of the main page in which I don’t have a blog up to now.
Thanks for your help,
Sparen
