Welcome to the Letβs Encrypt Community!
The command apache2ctl is not a very commonly used command, and with a good reason. Like Osiris said, itβs best to run
Also, please show the output of sudo systemctl status apache2
@Osiris@Litbelb thanks so much for your prompt help! I was able to fix the problem by first disabling all sites from /sites-enabled, then stop the apache2 server and restart it. also i did some changes in all the .conf files regarding all the sites from /sites-enabled. now my webserver is working again. thanks a lot for your help and input!
@rg305 sorry, I'm a new user and therefore only alowed to mention two users at one time...
