First time every using aaPanel and really liking it!
Setup a new VPS to try and added a few domains. All seems to work perfectly and do not see any errors in aaPanel area. Using Ubuntu 20.10 (GNU/Linux 3.10.0-1127.8.2.vz7.151.14 x86_64)
Apache showing fine in aaPanel:

While trying a few things in terminal (SSH), I discovered that Apache2 would not (re)start? Very confused. Shows fine in aaPanel but not in terminal. Hoping someone can enlighten me by looking at few logs below.
Many thanks.
