This might work. In the postbit template scroll down about 60% and modify the red conditional

			<vb:if condition="$show['postedited']">
			<!-- edit note -->
			<blockquote class="postcontent lastedited">
				<vb:if condition="$show['postedithistory']">
					{vb:rawphrase last_edited_link_by_x_on_y_at_z_postid, {vb:raw post.edit_username}, {vb:raw post.edit_date}, 
						{vb:raw post.edit_time}, {vb:raw post.historyurl}}
				<vb:else />
					{vb:rawphrase last_edited_by_x_on_y_at_z, {vb:raw post.edit_username}, {vb:raw post.edit_date}, {vb:raw post.edit_time}}
				</vb:if>
				<vb:if condition="$post['edit_reason']">
					<span class="reason">{vb:rawphrase reason}:</span> {vb:raw post.edit_reason}
				</vb:if>
			</blockquote>
			<!-- / edit note -->
			</vb:if>
			{vb:raw template_hook.postbit_signature_start}	
		        <vb:if condition="$post['isfirstshown']">
				{vb:raw ad_location.ad_showthread_firstpost_sig}
			</vb:if>
			<vb:if condition="$post['signature'] AND THIS_SCRIPT != 'private'">
				<blockquote class="signature restore"><div class="signaturecontainer">{vb:raw post.signature}</div></blockquote>
			</vb:if>
			{vb:raw template_hook.postbit_signature_end}
