500 error Configuration Information

[withypitts]

AT WITS END.

 

I have a problem with the Checkout process.  Customers are not able to pay because "Payment Type not Selected".  I understand this may be an issue with County / Currency setting in Configuration.

 

When I go to >Advanced Parameters >Configuration Information all I get is a 500 Error.  I have checked and amended Permissions in Config folder.

 

My customers are not buying from me becasue they cannot check out and pay.

 

I am losing business during a busy time of my year.

 

What should I be looking at to fix this fault?

 

Thanks for any help anyone can give me,  Richard

So the situation has changed.  

 

The error is now "No Payment Modules have been installed."

 

We have the standard Paypal and Bank Wire installed and enabled.  Also, Payment on Collection is installed but Disabled.  In the Payments Module Country restrictions are set as:

 

Pound Bank Wire and Paypal checked

Customer Currency Both unchecked

Shop default currency Both unchecked

 

Please mark each checkbox for the currency, or currencies, in which you want the payment module(s) to be available.

 

This implies that Paypal button can be schecked for all but it will only allow one button to be checked.

 

 

 

This error is occuring randomly as some customers are managing to checkout and pay.

 

 

Any ideas?
