invalid request after paypal click

[vkmaerkg]

if user adds a product to cart and click on paypal button (from here http://hclweb.it/sito-web-gratis-paghi-solo-hosting/i-nostri-lavori/ )there are 2 cases:

1 – if the user is not registered the browser shows a blank page whith a text in the up-left corner: invalid request

2 – if the user is registered the payment goes on, but in the up-left corner there is the text “invalid request”.

can you hel me?

Now I have unchecked the option for block the user unregistered (wpEstore -> addon setting -> wpEmember –>

Only Logged In Members Can Checkout) but I need to solve the problem!

thanks a lot

Basically you have a plugin that is outputting “invalid request” in the WordPress system (this is not good).

Do this test and find out which plugin is outputting that text in the WordPress system.

I’ve found the bad plugin!!! Thank you very much!

The plugin is:

Download Manager 2.0.2

Probably the error is that the plugin is not compatible from the wordpress 3.0.5 and I have the 3.1 version.
