Describe the bug
I rebooted the raspberry, then my phone cannot connect to the wifi, checking in the web-gui the dnsmasq service is stopped, and I cannot restart it.

Doing sudo service dnsmasq status I get:
illegal repeated keyword at line 6 of /etc/dnsmasq.d/090_raspap.conf

and in the these are the contents of: /etc/dnsmasq.d/090_raspap.conf

interface=wlan0
dhcp-range=10.3.141.50,10.3.141.255,255.255.255.0,12h
log-dhcp
log-queries
dhcp-option=6,1.1.1.1,8.8.8.8
log-facility=/tmp/dnsmasq.log
conf-dir=/etc/dnsmasq.d

This is a consequence of installing Pi-Hole alongside RaspAP. The error thrown by dnsmasq is your answer: the log-facility option is used in another config. Check the files in /etc/dnsmasq.d/. It does not matter if Pi-Hole is stopped; a conflicting directive like this will prevent dnsmasq from starting.

The FAQ offers numerous solutions to this.
