Hi everybody,
Many of users have posted an issue that they have been redirected to home page/index.php page after entering username and password on sellacious backend login page.
It's because of $live_site, those who are facing this issue they must have added $live_site URL in configuration.php.
Solutions are:
Remove $live_site url from configuration.php
OR
Add below code in this path
sellacious/includes/libraries/application.php on line 71,
JFactory::getConfig()->set('live_site', '');
Thanks
