Hello tim,
I was able to enable php error logging via htaccess
e.g.
php_flag log_errors on
php_value error_log /www/htdocs/myaccount/mydomain.com/errorlog.txt
I have repeated my steps in wordfence but nothing was logged inside the logfile.
My hoster told me that I can't access the apache error.log because it's "shared hosting".
Thanks,
Ferhat
