InfiniteWP is an awesome tool that makes it possible to update WordPress across multiple sites from one place. If you are using it on your server, you need to limit access to your IP only just to be safe. To do so, simply go to Settings > Security and whitelist your IP.
What if your IP changes? That happened to me just a few weeks ago, which led to loss of access to my InfiniteWP admin panel. The good news is there is an easy way to fix that. Simply open your database using phpMyAdmin and insert you new IP into the iwp_allowed_login_ips table.
The above screenshot shows a simple statement you can use to insert new IPs into your table. Don’t forget to change your database name and IP value. Of course, you could always reset your table when in doubt.
