I probably made a mistake in my request in the event that I'm looking to create a theme and I can't use /u/ or /u/unique_username I'm looking for the code or link that allows me to create a button for all users so anyone clicks on this button and it will redirect to their profile if I enter my username as you mentioned it will redirect all users to my profiles it's not what we're looking for

Thanks for taking the time to discuss that, I'd love to learn more about this area. Would you mind updating your blog post with additional details? It will be really helpful for all of us. You can play: fnaf security breach to relax, or pass the time!

Yanick,
I showed you two example links which way to address a Ossn user's profile page.
If this isn't working the same way at your site, please provide more information and the exact link you have tried.
See https://www.opensource-socialnetwork.org/wiki/view/1101/how-to-report-a-bug-error-issue

sorry for the message before

 your_ossn_site_url/u/unique_username

when I do your_ossn_site_url/u/unique_username the page tells me error 404 is this normal

The main link to any profile page is
your_ossn_site_url/u/ plus the unique_username
like
https://www.opensource-socialnetwork.org/u/secretmoon
https://www.opensource-socialnetwork.org/u/arsalanshah

I found a solution to my problem using components already on the website. But I would like to know the main link to go to the profile

I am sorry Yanick, I don't understand any of your topic you created correctly.
