Several days ago I couldn\'t access the admin panel on my site based on prestashop platform. After entering login and password, I was redirected to login page again and ever
I use prestashop 1.4.8.2 I just debuged my back office login loop by changing admin/login.php Just remove seemingly useless conditions in following code.
if ((empty($_SERVER['HTTPS']) OR strtolower($_SERVER['HTTPS']) == 'off')
AND Configuration::get('PS_SSL_ENABLED'))
Change with
if (!Configuration::get('PS_SSL_ENABLED'))
I also cleared cookie and bam it worked. I don't know if it will mess other stuff but I can AT LAST get in my back office. Peace!!
