The removal of IP logging from the table was actually a bug. For some reason one of the revisions dropped the hash and ip columns from the table. I just pushed up 2.5.4 which should re-add them to the btx_form_builder_entries table.
]]>When you removed the IP address feature from form builder, the "IP Address of Submitter" label still shows up when viewing an entry. In view-entry. php, you would want to remove the code below.
Version 2.5.2
<fieldset class="form_builder_entry_right">
<label><strong>IP Address of Submitter</strong></label>
<p><?=$entry["ip"]?></p>
</fieldset>
