I am trying to customize the text and URL for these two buttons in my community. I cannot see where to edit URLs or text, any help would be appreciated!

To adjust the text of the sign up button, you can use the Language system. You can read more here: https://invisioncommunity.com/4guides/themes-and-customizations/languages-and-localization_326/translating-using-the-standard-editor-r120/

To change the URL, you would use the Redirect to External site option in ACP -> System -> Login & Registration -> Registration.

Thanks! @Jim M I am unable to find in the language system where it says "Sign in with your Nursa account - or create one." I tried changing a few but there were no changes to the image I shared.

Is it perhaps a custom SSO solution that you have? If so, you would need to speak to the author

That language string is sign_in . You can find it in the Language/Translation section of the AdminCP. It looks like it has already been customised, though, that is not the default text.

It might be the custom SSO, but the developer that worked on it is no longer able to help and im not sure where to edit myself. The string sign_in doesn't have any customization next to it, so I am assuming it has to do with the custom sso?

Also, where would I be able to change URL for the community login (https://community.nursa.com/login) so I can add a UTM to track this?
