Cannot Add Or View Catagories And Products After Install

Hi y'all, just installed CS-CART v4 on Unix running PHP 5.3.27. Installation went fine, database connected etc. but when we try and add either a catagory or product it goes to a page that can display the background and pop up alerts - but nothing else.



We can add products and catagories using the bulk-add feature, but you cannot edit the products, or view the individual products as a customer on the site - it returns a blank page:










One last piece of info - we can't seem to activate the SEO addOn although we've followed all the instructions we've read online.

...oh and nothing shows in the error log!

Cheers!

Have got ISP to activate error log:



[05-Mar-2014 13:21:43 Europe/Moscow] PHP Fatal error: Uncaught → Smarty: Unable to load template tygh 'addons/discussion/views/discussion/components/average_rating.tpl' in 'addons/discussion/hooks/products/data_block.pre.tpl' ←

thrown in /hsphere/local/home/coolaz730/coolazstore.com.au/app/lib/other/smarty/sysplugins/smarty_internal_templatebase.php on line 127

OK, noticed that addons/discusssion template finding was the ish, so disabled it in AddOns. Can now +catagories and +products…

Well, you can't have everything - you cannot Quick View (Oops Internal Error!) or expanded view the added products (blank (white) page) when in customer view of the site.
