Can you run the database test script and paste the result here?
Version: 1.3
Found /var/www/nerdoflinux/wp-config.php.
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)
I understand the issue. See this discussion: https://ww.wp.xz.cn/support/topic/cannot-retrieve-user-options-from-database-2-3/#post-6218177
Follow the same instructions, except that you need to use this code (instead of wp_x2_):
/*
$table_prefix = 'wp_4_';
*/
