I'm in the final stages of customizing a brand new website. I thought I finally had everything under control, but I must have done something wrong at the last minute yesterday, because today I'm getting the error message, "Please contact the store owner; some required elements of this page are missing," when the program switches from tpl_login_guest.php to tpl_checkout_one_default.php. When I hit F12, I am told that jscript is saying that "Missing #orderTotalDivs" is the culprit, but I'm not entirely sure what that signifies. I made some modifications to the classes/order.php file, but I have not touched the classes/order_total.php file. Moreover, reverting classes/order.php to the original file doesn't fix the problem. When I click the "OK" button on the error message, the program resumes and lets the transaction proceed all the way through without further complaint. Any ideas? Thanks!
What template is in use? Those "missing elements" messages come from the OPC jQuery when it is looking for required "CSS Selectors", many of which (especially the order-total related ones) are customizable in the admin's Configuration :: One-Page Checkout Settings.
