NodeHam this is not related to a remote user account, right? But a local account?

To be safe, what you do mean by remote user account? It's a user on nodebb itself so I suppose that means local.

NodeHam yes, a remote account would be an account on another NodeBB forum, for example, reached via federation.

So you're able to access both user pages? What happens when you type ajaxify.data into the browser dev console on both pages?

Got it, no federation at all, single site on its own.

I'm not terribly concerned about the slug at this point. The email logo was fixed by editing the file and that's what I'm mainly nervous about.

ajaxify.data
{uid: 49, username: 'HelpSupport', userslug: 'helpsupport', email: 'support@mynodebb.com', email:confirmed: true, …}

NodeHam thanks, and what about at the new url?

Sorry, are we talking about the image or the user now?
The image url is correct but emails do not have that, they have the old url without the edited file.
It's like something got 'stuck' for lack of better word.

NodeHam any chance we can see this site?

Sure, in this case, it's https://support.isptracker.com/

Ok so, there's already an update but I need to solve this before I can update or have to edit the file again.

NodeHam I'm sorry, have been busy with other tasks and have not found the time to take a look yet.
