Baffled by "Fatal error"

donnelj · February 22, 2013

I'm on OSC 2.3 and I'm getting the following error at the bottom of most of my product pages:

Fatal error: Call to a member function display_price() on a non-object in /home/*******/public_html/shop/includes/modules/also_purchased_products.php on line 63

I also notice that my logo does not appear on pages that produce this error. Strange thing is that the error does not happen on any of the products in the 'Apparel' category. I've spent hours going through code line by line and I'm at my wit's ends here. Any help would be greatly appreciated. The store url is http://www.dwbrewproducts.com Thanks!

Here is the code for also_purchased_products.php:

You should as your first port of call, seek support from the template vendor.

MrPhil · February 22, 2013

$currencies is undefined. It's not set locally, and I don't see any 'include' or 'require' to bring it in (or the code to set it). Is that the entire file? If not, is $currencies set somewhere above (before) in a different function? Maybe a "global" statement is needed. Have you modified the code in any way (installed add-ons, etc.)? Is this a template from a third party vendor?

Thanks for you response Phil

Is that the entire file?

Yes that is the entire file

Have you modified the code in any way (installed add-ons, etc.)?

There have been a few addons installed but "also_purchased_products.php" has not been modified.

Is this a template from a third party vendor?

Yes this is a template from TemplateMonster. I was called in to help on behalf of my friend who is the site owner. He tried to get support from the vendor but they are not very helpful. Posted on this forum in hopes that someone may have experienced a similar error.

MrPhil · February 23, 2013

The also_purchased_products.php you listed appears to be an almost total rewrite of what is shipped with osC. Not knowing whatever other changes they made, I can't offer any help on this. Sorry.
