Hello,
I just installed the version 1.4.0 (in Phoenix 1.0.7.14) and found a bug preventing adding 'Required ip':
in includes/modules/store/st_store_mode.php
in the function htaccess_backup the line:
if ( defined('MODULE_STORE_MODE_ALLOWED_IPS ') && tep_not_null(MODULE_STORE_MODE_ALLOWED_IPS) ) {
contains an extra space before the closing apostrophe and should be
if ( defined('MODULE_STORE_MODE_ALLOWED_IPS') && tep_not_null(MODULE_STORE_MODE_ALLOWED_IPS) ) {
