how can we edit the account activation email that is sent to users?
If I remember correctly it's a language file/setting.
where that file is located?
Go to
./inc/languages/english/messages.lang.php and find:
$l['email_activateaccount'] = "{1},
To complete the registration process on {2}, you will need to go to the URL below in your web browser.
{3}/member.php?action=activate&uid={4}&code={5}
If the above link does not work correctly, go to
{3}/member.php?action=activate
You will need to enter the following:
Username: {1}
Activation Code: {5}
Thank you,
{2} Staff";
