I have seen a few posts that were somewhat like the issue I'm experiencing, but not exactly...
when we go to the checkout on my site there are a few possible problems. if, in my config, i have credit cards set as my only possible payment option, then the radio button next to the credit card graphic is greyed out, and there's nowhere to enter in the credit card number, expiration date, or ccv.

if i configure to also accept Paypal as a payment option, then there is the credit card graphic and the paypal graphic. both radio buttons are selectable, and if you select paypal, and then REselect the credit card option, suddenly the window to allow entry of credit card data is visible.

Does anyone know what is causing this issue, or where there's a similar forum post with an answer to this issue?

thanks in advance for all your help, Ubercart community!
