It seemed weird that I was experiencing this problem without having updated the plugin, so I checked the readme.txt file on the server and sure enough it’s for v6.0.2 I’m really scratching my head about that because I didn’t do it, or if I did I don’t know when or how. * Randall * [OneHundred](https://wordpress.org/support/users/onehundred/) * (@onehundred) * [10 years, 10 months ago](https://wordpress.org/support/topic/inet_pton-issue/#post-6152535) * I have also posted this in another thread: * > I’m experiencing the exact same error code today (since the update).
