Customer Can't log in only if i register a new user it automatically goes to my account. However if i try to login with a existing user it refreshes the page.
I already tried to insert
<?php echo $this->getBlockHtml('formkey'); ?> into the different login.phtml
that didn't work so i tried with
<input type="hidden" name="form_key" value="<?php echo Mage::getSingleton('core/session')->getFormKey(); ?>" />
right below the tag and that didn't work either.
