why I cannot edit product in admin?

[lina0962]

I don't know what happened. Suddenly I cannot edit product in admin. When I click the "edit" button in admin-Categories / Products, the page goes to "Page not Found"

And when I click the product (named "test") on the storefront, it goes to "Page not Found" too!

I must did something to blow everything up! But I don't know how I messed it up and how to fix it? Please help me!!

The site is www.best4future.com, click on the "test" or "this is a test", you will see my problem.

You seem to have several mods installed. Try disabling the mods one at a time and see whether they could be the cause of your problems. In your case, your template could cause problems.

Do note that you should avoid making changes directly to the Classic template and make use of Template Overrides method for your design instead. This will help in your troubleshooting and future upgrades.
