[SOLVED]Refresh problem

[mickeyboy1]

Hiya all,

I have a problem with my site not showing the "Add to cart" button on products with attributes.

When you first goto a page, the "Add to cart" button is not visible, but if you refresh the page(f5) then the "Add to cart" button appears.

Problem page url= http://www.biketuna.co.uk/shop/pro-bolt-special-parts/352-probolt-aluminium-gear-shift-rod.html

 

I have used the developer tools in chrome and when you first visit the page it shows the following in the before refresh.jpg below

And after you refresh the page it shows the following in the after refresh.jpg below

 

Any help is greatly appreciated

 

Thanks mb

 

Forgot to say i am using prestashop 1.5.3.1

Hiya jiten, 

i removed them from product.tpl but its still the same

 

Any other ideas please

[Jiten rash (away)]

 #add_to_cart {display: block !important;}

 

add this any were in the global.css

Thanks again for the reply Jiten, but it was more than just the add to cart button not showing.

 

I think i have fixed this refresh issue......

 

In my header.tpl i had

<script type="text/javascript" src="{$js_uri}" async></script>

I removed the "async" and it seems to be working fine now

 

Does anyone know why adding "async" would stop some of the javascripts loading until the page is manually refreshed ???

The error message you got said that "$" was missing. $ is a central variable in jquery. So I suppose that by declaring asynch you delayed loading jquery. And as many PS scripts depend on jquery they couldn't work.

Thanks for explaining this musicmaster..

 

I have previously used gtmetrix and to help with the page load speed it suggests adding async to the script tag

 

But it obviously doesnt work so will leave it as it is

 

Thanks for all the replies

 

Shall mark this topic as solved
