I'm trying to upload all my products via .csv (around 2,500) and followed all of the formatting properties in the documentation and getting the following error:
Warning: strpos() [function.strpos]: Empty delimiter in /sitepath/product_options.tpl.php on line 53
All products are being imported fine and into their right category but this error appears on the product page. Not sure what to do.

Using CS-CART: version 2.1.2 PROFESSIONAL
