GPG is not working because of gpg.conf

[Basix]

Hello, I'm a user of GPG and I got some problem.

Recently my machine showing this message when do something in GPG:

[sample at localhost ~]$ gpg
gpg: /home/sample/.gnupg/gpg.conf:5: invalid option
[sample at localhost ~]$ cat -n ~/.gnupg/gpg.conf
     1	
     2	###+++--- GPGConf ---+++###
     3	utf8-strings
     4	debug-level basic
     5	log-file socket:///home/sample/.gnupg/log-socket
     6	###+++--- GPGConf ---+++### 2018년 02월 22일 (목) 
     7	# GPGConf edited this configuration file.
     8	# It will disable options before this marked block, but it will
     9	# never change anything below these lines.

I think Kleopatra or another GPG frontend misconfigured my gpg.conf. How do I fix it myself? My GnuPG version is 1.4.22.
