FIX – Customer cannot login to magento 1.8.1
April 02, 2014 | Write by
Following an upgrade to magento 1.8.1 on our development servers , we noticed that customers are unable to login to their account. The issue is raising because the custom login form does not contain any form_key and there is a form key validation happening in loginPostAction of magento. Here is the solution: 1 – Go to template/customer/form/login.phtml and template/persistent/customer/form/login.phtml and under
<ul class="form-list">add the following code in the login form
<input type="hidden" name="form_key" value="<?php echo Mage::getSingleton('core/session')->getFormKey(); ?>" />If you are using the login form in different templates then you use add the form_key to the other parts as well. I hope this helps. EDIT: – We are aware that this issue also exists while updating the qty of cart items, the same solution applies there. – Previously there was two methods in this blog to fix the problem but editing core files goes against Magento development standards hence that has now been removed.
