CartThrob Product - Simple FT not rendering

Question

I recently upgraded CartThrob 2.61 to v 2.71 on my development server.

After updating modules, everything seems to work fine except for when I try to render a CartThrob Price - Simple fieldtype in my templates.

Using the following test example on a development page, the page loads continuously before timing out. So I have no use of the template debugger or the profiler to help me out. There are no PHP errors or Apache errors for me to trace either.

{exp:channel:entries channel="products" limit="10"}
    {exp:cartthrob:add_to_cart_form entry_id="{entry_id}" 
    }
        Title: {title} <br/>
        Price: £{product_price} <br/>
    {/exp:cartthrob:add_to_cart_form}
{/exp:channel:entries}

Has anybody come across anything similar? Can anyone give me any tips on how to begin to debug this?

Answer 1

I had recently installed the CartThrob Subscriptions module alongside the new 2.71 CartThrob Pro upgrade.

After doing some laborious debugging work, uninstalling and reinstalling the CartThrob module, I discovered that the EE channel assigned to serve as the Products Channels for the CartThrob Pro module (Store - Channel) had been reassigned to a new channel created by the installation of CartThrob Subscriptions (Store - Subscriptions).

Because of this, all my field mappings had been lost. Therefore no values were being assigned to any of the CartThrob Price - Simple fieldtypes for my products.

Rather than be informed of this with a notification or even a PHP logged error, I was given nothing. Poor form CartThrob and Vector Media Group.

You just wasted 4 hrs of my time.
