DHTMLX Suite 3 Skin Builder

Suite and Optimus Suite 5
#1

I have a website using dhtmlx 3.6 and I need to adjust the skin.
https://dhtmlx.com/docs/products/skinBuilder3/
can’t use because the iframe source is referencing http instead of https
I know it’s old, but you used gifs for background instead of color - can you fix for me?

<!-- skin buuilder container -->
<div class="internalpage_content" style="margin-top:20px;">
	<iframe border="0" frameBorder="0" style="position:relative;width:100%;height:1030px;margin:0px;padding:0px;" src="http://apps.dhtmlx.com/skinBuilder_v35/skin_builder.php" scrolling="no">	
</iframe>
</div>

Hello.

I apologize for the delay. We have updated the url, but unfortunately, this skinBuilder source is not present anymore.

I can only suggest you use a more recent dhtmlx 4-5 with its skinbuilder:

sorry for not so good news.
