Admin Email and Newsletter Function leaves blank page after upgrade to 1.3.8?

I upgraded my cart to 1.3.8 and now when i got to /tools/send email it just brings shows a blank page and it shows that it is loading then after like 5 min it loads but it does not show any of the customers to send an email to. How can I fix this.

Thanks

How many customers do you have?

10344 customers It worked just fine before I upgraded

The Send Email is drawing a dropdown with 10344 email addresses ... that is at least 10344 lines of code ... :eek:

That has to draw and download to your computer ...

You could customize that to not draw the dropdown ...

For the Newsletter, I would get a real Newsletter email software package or service to manage this once you go over 500 to 1000 depending on your server and the rules for your email with your hosting provider ...

Your server may be underpowered to handle a new customer distribution group added in 1.3.8. You can disable it by following my post here: http://www.zen-cart.com/forum/showthread.php?t=101799
