I tried to amend my profile but it takes me to another user (Chris878), can someone please fix this?
Darren already explained this.
You have a '.' at the end of your username, this screws with the SEO which seems to ignore them and take you to the first user who has a username srating with 'Chris' and having symbols/numbers after it.
Darren does not have symbols/numbers in his username thus this doesn't cause the SEO issues.
If you would like to change your username to something that doesn't end in a symbol/number, let us know and this should (I think) solve your issue.
