Product Tags breaking Loop

Hello,

When I enable to option ‘product tags’, for some reason the products do not show on the search page.

I can see ‘showing 1-16 of 174 results’, but inside the product loop there is nothing. When I try ‘var_dump’ on ‘the_post’ inside the loop, it returns NULL.

When the plugin is disabled, or the ‘check product tags’ option is disabled then it returns fine.

Worth noting that this only happens on page 1.. page 2 shows products fine.

Any thoughts?

Thanks,
Regards,
Lewis
