Problem loading any page

I'm just getting started with HikaShop Essential. I can't get any products or categories to display. I have all the modules enabled. I tried loading a products listing, a products page and a category listing through a menu and no matter what I do I get a "problem loading page" error when I test the menu. I also tried creating a menu module and get the same errors. I've tried everything on the "Content display on the front end". I think I've read all the documentation on the subject but I must be missing something in the Hikashop configuration. I appreciate any guidance. website is www.phoenixrbt.com . Thank you.

I have five menus published because I was trying different options in an attempt to figure out what I'm doing wrong. There's a module on the right hand side that has three menus: UTM Kits and Ammmo, NLTA Protective Gear and Portable Training Facility. I also have 2 sub menus under the UTM top menu option. If you hover over UTM (on the top menu) you'll see UTM Ammunition and Conversion Kits. They are both trying to open a product page/listing. Thanks for taking a look. Dan

I've installed ARTIO JoomSEF extension. I haven't changed any of the settings for SEF in joomla. I'll look at the settings now and try to print a report. Thanks

If I can't get joomsef to work with hikashop do you have a SEF program that you recommend? thanks again for the prompt support. I've been trying to figure this out for a few days and was getting pretty frustrated. Thank you.

I didn't realize Joomla had built in SEFed URLs. I'll try to figure out how to enable that and I'll uninstall the joomsef. I'll let you know if that doesn't fix my problem. Thanks again. Dan
