Paypal express payment form page styles

Hi

Does anyone have any idea why my paypal express payment page is randomly displaying a generic payment page instead of the custom page styles I have set? Is anyone noticing this happening with their paypal express checkout?

I have my custom payment page set up in my paypal profile. I have the correct page style name added to my paypal express api. Sometimes my custom payment page comes up but lately, more often than not a very generic, streamlined version payment form is displaying. I switched my template to classic which made no difference. My page styles always used to display correctly. I spoke to someone at paypal who couldn't determine the cause. She did see the generic paypal payment form when doing checkout from my site. She went to her own website (not a zencart) and had no problem seeing her own customized paypal payment form. This is happening with my 1.5.0 cart and my 1.3.9h cart. It's not just my own cart though. I see it happening with a 1.5.1 cart. I've searched online and haven't found any solution. I did find this old thread and don't know if what Dr. Byte says from post #9 still applies. http://www.zen-cart.com/showthread.php?50910-Logo-doesn-t-show-up-on-PayPal-checkout-page. I don't see "page_style" in view source of my confirm order page as mentioned in post 9 from that thread. I tried removing and reinstalling paypal express api and that didn't make a difference. At a loss.

this is a screenshot of the generic paypal express payment page that's been displaying.

I finally got to the bottom of this problem. This old post confirms the problem and the cause.

removed link

The Header Image URL is the problem on paypals end. I removed my custom Header Image URL and instead added a custom Logo Image URL: and it cleared up the problem. Not how I want it, but that was the problem

edit: woops I guess I can't post an outside link so I removed it
