Blank screen on checkout-payment after upgrading to 1.3.8

I have just upgraded the first of a few sites to be done (1.3.7.1 > 1.3.8). The site isn't live as it is still being developed.

After upgrade I have a white screen on checkout_payment, I thought this would be the ceon_manual_card contribution throwing up an error but after removing this and using cod I still get a white screen?

Has anybody else seen this?

Contributions installed...
Ceon Manual Cards
Edit Orders
Image Handler 2.0
Better Together

It seems the culprit is the better together contribution, with this removed everything seems to be functioning...

I have the same problem upon upgrade - BLANK SCREEN on Checkout Payment and do not have those mods.

Please HELP

What have you got in Admin > Modules > Order Totals?

COD Fee ot_cod_fee
Discount Coupon ot_coupon 200
Group Discount ot_group_pricing
Gift Certificates ot_gv 840
Low Order Fee ot_loworderfee 400
Quantity Discount ot_quantity_discount
Shipping ot_shipping 325
Sub-Total ot_subtotal 100
Tax ot_tax 300
Total ot_total

I guess the only "mod" would be QUANTITY DISCOUNTS, but I tried disabling that and still the BLANK SCREEN

If you simply "view" all three Modules pages in the admin, and then go back to the storefront, do things work correctly?

• Payment
• Shipping
• Order Total

If not, please list all the addons/contributions used on your site, and which Zen Cart version you're upgrading from.

Remember, the upgrade instructions tell you to remove and re-install all shipping and payment modules affected by the upgrade.

After removing QTY Discounts and getting the blank screen, I refreshed the page and now the page appears.

It appears the culprit is QTY DISCOUNTS. I really need that mod to work though.

thanks

Seconded - Just disabled the Quantity Discount module - checkout_payment now works. No errors flashed up in the apache logs

Just found this RE: Quantity Discounts - swguy has released a patch :clap:

I don't have that module installed, and yet am getting the same error.

I get to page 3, Order confirmation. And when I click the continue button, I get nothing but the black screen.

The only modules I have installed are the ez populate and and the user tracker. (and one theme)

everything is basically straight up Zen Cart with some cosmetic changes (mostly in the language files, i.e. changing "Model" to "SKU #"

What have you got in Admin > Modules > Order Totals?

If you have any additions outside of the standard zen cart ones?

COD: Fee ot_cod_fee
Discount Coupon: ot_coupon
Group Discount: ot_group_pricing
Gift Certificates: ot_gv
Low Order Fee: ot_loworderfee
Shipping: ot_shipping
Sub-Total: ot_subtotal
Tax: ot_tax
Total: ot_total

If you do, try turning them off and trying your checkout again.

Nope, no additions in the Order Totals section at all.

in fact, I have COD and Low Order Fee turned off completely

and no new modules in that area, or in the payment area either

in my testing, I am using GV to pay for the item.

When I forget to put in a GV amount, it will take me from the confirmation page to the paypal pages.

But if I put in the GV amount, I get the blank page instead of the "completed order" page

ideas? suggestions?

index.php?main_page=checkout_process is where I get the blank page...

'Fraid thats a different error to this one more likely to be a misconfigured payment module (paypal??)

Try raising a new topic in the upgrading forum

I meet same problem.
Just remove all payment , shipping mothod and reinstill the payment and shipping in the admin. solved the blank problem.

good luck

Moderator note: These steps are included in the upgrade instructions ... don't forget to read the instructions!

Just wanted to say a quick 'thank you' to fiji for taking the time to post the solution to your problem.

I had just spent about 20 hours over two days upgrading from 1.3.7 to 1.3.8a and then customizing with templates and mods. Made numerous backups at various stages along the way, and tried each mod as it was added to be sure everything was ok.

Then somehow (?) earlier today my checkout just stopped working and I got nothing but a blank page after customer login.

I spent the last two hours tediously going through file comparisons, and db comparison trying to find the problem/solution.

To give my mind a break I decided to check the forum here to see if anyone else had the same/similar problem.

Found your post, did as suggested, and now everything is working great again.

If you ever find yourself in the U.S. I owe you a beer! :bigups:

I did removed all payments and all shipping and just installed PayPal Express and USPS and everytime it goes to checkout_payment I get the blank page.

Now if when showing the shopping cart, I click PayPal it goes trhough all the process and when exit PayPal that comes back to my site, it shows the Confirmation.

So I guess the Clicking Checkout Directly is looking for a Direct Gateway Credit card process. But I dont know Im newbie.
