First, Welcome to Hive.
Are you using Chrome or a different browser to try and change your settings? The old version of Edge and IE sometimes have problems with Hive. Next, are you trying to change the settings on hive.blog or peakd.com? These are the two most popular Hive front ends. If one is causing you problems try using the other one to change your settings.
Very helpful advice here and I appreciate the welcome! I am indeed using Chrome. I had tried peakd.com before but could not access it using the Hive keychain extension; I have just tried again using an alternative login method and had much more success, thank you! The peakd.com aesthetic is quite an upgrade in itself.
I left an invitation on your intro post to The Terminal, please come in if you have questions, there are knowledgeable people there and we can help you if you wish. JamesThere are more suggestions such as using keychain to log in with @jaxdidit, it complements peakd.com very well.
