Opening it for reading. Looking for DB_NAME, DB_USER, DB_PASSWORD, DB_HOST and $table_prefix: DB_NAME: found ‘[hidden]’ DB_USER: found ‘[hidden]’ DB_PASSWORD: found DB_HOST: found ‘ localhost’ table_prefix: found ‘wp_’ Attempting to connect to the DB: OK Attempting to read NinjaFirewall’s options (nfw_options) from the DB: OK Calling fetch_object: Error: Exiting. I removed the DB Name and User for security reasons. I suspect the problem is because its a multisite, so the DB prefix is wp_4_options(that’s what other plugins say) * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[WP Cerber Security, Anti-spam & Malware Scan] inet_pton(): Unrecognized address](https://wordpress.org/support/topic/inet_pton-unrecognized-address/) * Thread Starter [nerdoflinux](https://wordpress.org/support/users/nerdoflinux/) * (@nerdoflinux) * [8 years, 5 months ago](https://wordpress.org/support/topic/inet_pton-unrecognized-address/#post-9769128) * I managed to fix it by manually removing the DB tables and reinstalling. I think the problem was it couldn’t write to the DB, so it couldn’t read the IPs, so it tried to pass an empty string, causing the error. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin] Registration page redirects to HTTP 500 error](https://wordpress.org/support/topic/registration-page-redirects-to-http-500-error/) * Thread Starter [nerdoflinux](https://wordpress.org/support/users/nerdoflinux/) * (@nerdoflinux) * [8 years, 11 months ago](https://wordpress.org/support/topic/registration-page-redirects-to-http-500-error/#post-9286264) * I managed to fix the issue.
