ADD TO CART BUTTON is disabled but not an inventory issue

[Ishah]

Hi all - i need a shopify whizz who can help me troubleshoot and fix a key issue in my store. My ADD TO CART button is disabled on all products in one collection only. 

It is not a product issue as I am not tracking inventory and I have tried to isolate shopify apps to see what is causing this but no luck.

App developers say its not their code causing it and shopify theme says not their theme so what could it be? 

Thanks for any help.

Hi @Ishah,

I checked and this error can be generated by app. Because I checked the theme code and didn't see anything causing this error.
You can turn off the app and test, I'm pretty sure the theme will work.
Hope it helps!

Thanks yes it could be an app. I have turned off all the apps and also touched base with app developers but nothing has changed. If there is a way to identify what app is causing it would be usefil because currently all app providers are claiming the issue is not their app and i have deleted the potential suspicious ones. so am really stuck.

Hi @Ishah,

Really couldn't find it through check the demo link. So you can disable each app and test it.

Sorry for this, but couldn't find any app's code.

Hope it helps!
