So, my WordPress site is having some random issues, and I can't think what could be causing them.
First of all, a couple of days ago, the wp_users table deleted itself. I've managed to recreate it from a backup, and restore all users.
Now however, my whole site is down. I added a user, and when I tried to go back to the dashboard all I can get is this error message:
ERROR: $table_prefix in wp-config.php can only contain numbers, letters, and underscores.
Is there anything that can cause this, or how I can fix it? I've checked the wp_config.php and everything seems to be in check, and all the tables start with the correct prefix, so I have no idea what's wrong.
