Unable to migrate beyond 2.0.24b

[Sadruddin]

I'm trying to update to 2.0.26d

I've backed up my whole site, and have a development copy.
THAT copy migrates up to 2.0.26d just fine.

But on my live site, if I try to go beyond 2.0.24b then while everything else works fine, on checkout (Paypal standard only) instead of going to PayPal, it displays the "Your Account Details" page, even though my account details are displayed on the cart page.

I use no SEF, don't use a commercial template, and One Page Checkout is not enabled.

I can't see any difference between my 2 databases.

Help?

The PayPal plugin has changed - make sure it is correctly configured.

Thanks.  Can you point me to where there are details of the changes, please?
Also, why would one version of my site work, and the other not?

Just look at the PayPal plugins! For configuration see http://forum.virtuemart.net/index.php?topic=122595.0

What are the differences in host configuration for the two versions?

[Sadruddin]

Thanks.

As far as I can see, the host setup is identical.
Same host, same versions of everything except VM.
Anything particular you'd suggest I check on, please?
