Bug/error in paypal and account edit. Business

I have this error on Checkout:

Please configure your payment methods
No payment methods found

I am still getting this error after following all suggestions in the support forum.
Using USPS shipment plugin and paypal basic plugin. I have configured all, saved and published trying various configs.
It was connecting to paypal before USPS plug was installed, but no config changes seem to make any difference.


In addition, I have an error in user account edit:

Warning: SimpleXMLElement::addAttribute() [simplexmlelement.addattribute]: Attribute already exists in /home/stevehhb/public_html/libraries/gantry/core/utilities/gantryjformfieldaccessor.class.php on line 37


Please assist. Thanks

Make sure that you don't have any shipping methods selected in the "shipping methods" restriction option of your paypal plugin and paypal will display.

For the error message. It's not related to HikaShop but to your template. Please ask your template provider for a solution.
All I can tell you is that if you set the "error reporting" option of the joomla configuration to "none", you won't get the error message anymore. But it would be better if they could fix their code.
Note that the user account page is a joomla page, not a HikaShop page.
