Product Comments fails

[candh]

Hello, I've enabled the productcomment module in my Admin panel. When I clicked to test the comment feature, I was shown the following errors.

 

Notice: Undefined index: product in /Users/candh/Sites/cache/smarty/compile/42/92/b5/4292b57f983b87f8f99e90da1d0835de6a62bf37.file.productcomments.tpl.php on line 166

I then cleared the cache by going to Performance and Clicking the "Clear Smarty cache and Autoload cache" button. It was successful. I checked again and the problem still exists. I then found this https://www.prestashop.com/forums/topic/302412-product-comments-errors-in-version-28/
But it was of no help because there is no $product variable being assigned inside

public function hookProductTabContent($params)

What can I do to resolve the errors?

I'm running PrestaShop 1.5.6.2
The productcomments version is 2.9.1 I've also checked with 2.9 and it didn't help.

 

Here is my hookProductTabContent($params): https://pastebin.com/dVZFXEKh

I !!fixed!!! it by clicking on the "Reset" from the modules page.

I also changed data: $('#id_new_comment_form').serialize() on line 66 on productcomments.js to data: $('#new_comment_form form').serialize() 
to make it work. 

!!CLOSED!!!
