If you somehow manage to ban yourself from your own site (most people seem to achieve this at
least once :) go to XOOPS_TRUST_PATH/modules/protector/configs and delete the files in there.
One of them contains the 'banned IP' data so getting rid of it (or better, editing it to remove your
own IP) will restore your access to the site. Note that deleting it will also restore access of all other
banned users, so editing it is a better idea if you aren't in a hurry.
In previous versions of Protector there was a facility to set a “rescue password”, but this has been
removed in V3.
