I have upgraded apache httpd server from 2.4.6 to 2.4.46.
When I fire systemctl start httpd it shows the following error:
Starting httpd: /usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd: undefined symbol: apr_procattr_perms_set_register
Either the apr apr-util package are missing or there was corruption during the installation of these packages. Could you please reinstall apr and apr util package and test.
