Thanks for the help Paolo!
As you stated, after moving the activate.php file over correctly and preserving the path/directory structure, I can now make changes to the activation page.
I managed to update the bit of code which redirects to the wp login to just the sign-up page.
On line 33 of activate.php:
<p><?php printf( __( ‘Your account was activated successfully! You can now log in with the username and password you provided when you signed up.’, ‘buddypress’ ), wp_login_url( bp_get_root_domain() )); ?></p>
search for:
wp_login_url( bp_get_root_domain() )
replace with:
‘http://lifeinmotion.ca/?geodir_signup=true’
I also found that leaving the bp_get_root_domain() bit and just removing the wp_login_url() function works well too if I just wanted the user to go back to the home page.
If I’m missing something, at least it is working as I expect now.
Thanks again!
