Product is not available when have attributes

[Hrist0]

Hello,

 

We have PS website, where some products are with attributes and some - without. When you click on the product without attributes - everything is OK. Example: http://www.guga.bg/en/push-and-pull-wooden-toys/7-rolling-snail.html

 

Problem is with product, who has attributes. When you click on it, first /for a short moment/ there is red label - The product is no longer at stock. After that- when it checks attributes stock, everything is OK. My connection is fast and it is just a moment, but for client with slow internet speed - this can be couple of seconds and client will click on other product. 

Example: http://www.guga.bg/en/globber-scooters/80-scooter-my-free-5-in-1.html

 

We also use custom script, where export from our ERP part number, stock and price and it goes directly in PS. 

 

We are also using good VPS with SSD and I doubt that this is server issue.

 

Does anybody has idea how to solve this issue?

 

Thanks in advance to anybody.

 

Regards

Hristo

I guess it depends on the template.

You can try hiding that with css/js and show it afterwards when the attributes load

Check for javascript errors. It may be that your script doesn't load in time and causes some error because of that.
