Currently, when I open a product page, I am presented with three buttons
If I click share, it redirects me to a login page. Why a person needs to be logged in in order to share something, I have no idea. Is there a reason for this? Can I fix this?
The only fix I have come up with is to use an extension call AddTo.
Here is a picture
If I click "Share", I am redirected to login.
If you are talking about the send to a friend feature, this can be activated for guest or only registered users.
In the controller Mage_Sendfriend_ProductController::preDispatch it checks to see if the feature is activated only for registered users via $helper->isAllowForGuest()
This helper function simply looks for the config value sendfriend/email/allow_guest this can be changed via the admin section Email to a Friend.
Simply - Overwrite - /vendor/magento/module-send-friend/Controller
/* if (!$helper->isAllowForGuest() && !$session->authenticate()) { ---- Before*/
if ($helper->isAllowForGuest() && $session->authenticate()) { /-------- After/
