Error roundcube imap

I have the following error:

[Tue Oct 27 13:45:54.445032 2020] [proxy_fcgi:error] [pid 5785:tid 139651616577280] [client 88.5.61.34:0] AH01071: Got error ‘PHP message: PHP Warning: file_put_contents(/var/log/roundcube/imap): failed to open stream: Permiso denegado in /usr/share/roundcube/program/lib/Roundcube/rcube.php on line 1259’, referer: XXXX

There is a solution, since I enter and I do not see any log file created
