I see there is a login issue after the 8788 update, but none of the solutions worked for me. I also uninstalled 8788 and still customers cannot login.
/template/persistent/customer/form/login.phtml is the file that shows. I also turned the theme back to base & default and still cannot login.
Go to Solution.
