products redirection

Looks like you have 2 pages called “Products”, one with the slug “products” and one “products-2” and so maybe there is a mixup there somewhere. Suggest you go through the list of pages and ensure you have only one page called “Products” with the slug “products” and delete any similar pages. Then go to Admin page > WooCommerce > Settings > Products tab > Display, and ensure the drop-down at “Shop” points to this “Products” page.

i have deleted that page and done the steps u told to perform.
actually u didnt understand my problem.
go to any of my woo categories. for example – https://www.globalpetrochem.in/product-category/automotive-lubricants-greases/2-stroke-4-stroke-engine-oils/

here u see 4 products are being listed.
now click on any one of the product.
then u will see that when u cick on a product the next page opens is not the page which is suppose to open i.e. the details about the product u clicked should be displayed .
instead a page is opened where all the wordpress post are being displayed.

Yes I got the problem but not the answer!

You are running the latest version of WooCommerce 2.3.7 but your theme is version 1.2.2 which is not the latest version. 1.2.2 says it is compatible with WooCommerce version 2.2.x. Version 1.3 of your theme says it is compatible with WooCommerce version 2.3.x. See the changelog:

So consider updating your theme, but take a backup first.

Also did you reset permalinks? Go to Admin page > Settings > Permalinks and click the “Save Changes” button.
