BuddyPress

When new users to my site register, they receive an email to activate their account. The link to activate the account leads to a blank page, thus making it impossible to activate their account. Any way to fix this?

It all depends on what’s happening here.

Could you go into your wp-config.php file and look for the line
define('WP_DEBUG', false);

Make sure this is set to true.

Re-visit your activation page and post the last error message you see (if any).

Also, in your BuddyPress theme could you find the file located here

wp-content/themes/your-theme/registration/activate.php

and post the code that’s within it please.
