with permalogin, no fe user can login
FE users couldn't log in. The newloginbox would show they are logged in, but going to another page or reloading the page would show them logged off. That happened with permalogin settings 1 and 2. Once I disabled that setting by setting it to -1, logins would work fine again.
PHP is 4.4.4, TYPO3 4.1.1
