The Paypal plugin seems to be incompatible to classic Tiki layout, as it paints the cart display partially over the Tiki window and partially (lower left corner) under the (middle section) Tiki window, see screenshot.
Two minor issues with this plugin: It ignores the global setting that decimal commas are to be used, and that the euro currency symbol is trailing (with a separating space).
Thanks
