line 48: syntax error near unexpected token

FYI, as of August 27, 2020, the current script 1.6.1 gives this error on a raspberry pi running raspbian buster. Pi-hole v5.1.2

pi@raspberrypi:~ $ sudo Pi-hole_SafeSearch.sh --enable [2020-08-27 14:30:01:998]: Retrieving List from Google [2020-08-27 14:30:03:287]: 191 TLDs [2020-08-27 14:30:03:297]: 382 Domains [2020-08-27 14:30:03:308]: ENABLING SAFESEARCH FOR PI-HOLE [2020-08-27 14:30:03:325]: BLOCKING OTHER BAD SITES /usr/local/bin/Pi-hole_SafeSearch.sh: line 48: syntax error near unexpected token^'
/usr/local/bin/Pi-hole_SafeSearch.sh: line 48: "(^|\.).+xxx$"'

In testing, it looks like line 192 is the one that is failing. If I comment it out, things work.
silently pihole --regex "${REGEX[@]}"

For clarity, here's what the REGEX code is:
REGEX=( "(^|\.).+xxx$" "(^|\.).+sexy$" "(^|\.).+webcam$" "(^|\.).+sex$" "(^|\.).+porn$" "(^|\.).+tube$" "(^|\.).+cam$" "(^|\.).+adult$" )

The log file has this in it:
`pi@raspberrypi:~ $ cat /var/log/Pi-hole_SafeSearch.sh.log

Sorry for the odd formatting, not sure why it isn't showing the code with the newline/CR.

Mmm... messing with it in an effort to debug it has caused it to start working. I'm not sure why. There's another person on this blog site in the discussion section at the end with the same error. I started thinking it was a bash thing. I tried:
sudo bash /usr/local/bin/Pi-hole_SafeSearch.sh -e

things started working but then it also worked running that without the bash in it. weird.
