Do anyone know if this works with vBulletin 3.8.8 Beta 2? :)

I am still using this with vB 3.8.9 PL1 and have one problem that I hope someone here can help with.

When members click on the Donate button, the PayPal page is shown in German with no way of switching to English.

With the Paid Subscriptions feature in vBulletin, I was able to fix this by adding the following to the template: subscription_payment_paypal

Just before <if condition="$show['notax']">, add:
That works fine for paid subscriptions, but this hack does not appear to use it.
What needs to be changed in order to get this hack to use that line and default donations to English?
