The dashboard gives me a warning that 7.3 is old and needs to be updated to at least 7.4. As soon as I upgrade to 7.4 I get a 503 error I can only fix by going back to 7.3. I would really like to upgrade but don't know how to get around the error.
I searched but only found info on PHP 8.
Running 3.7.24 with WP 6.1.1
Thanks!
