I can’t access my site anymore.
This could happen for various reasons, such as:
your IP address was automatically added to the Blacklist area
you accidentally added your own country to the Country block area
you haven’t allowed your user to access any component from within the Joomla! administrator area
forgot the additional backend password
To overcome these restrictions, you will simply have to open your FTP account, head to:
/plugins/system/rsfirewall/ and rename rsfirewall.php to rsfirewall.php.bak
This will automatically disable the RSFirewall! System plugin, thus the firewall restrictions won’t be applied.
Once you have completed the above step, you will be able to access your Joomla! administrator panel as you would normally do and revert your RSFirewall! settings. After you are done, remember to rename the file back.
