Blank page when generating ckeckout/invoice right after submitting an order.

[hostingstudio]

Dear friends,

 

I am having a very strange problem with my WHMCS 5.3.10, which I use with default template.

 

If a customer places an order, and then clicks to proceed for payment, the following URL returns a completely blank page:

 

https://www.xxxxx.yyyy/cart.php?a=checkout

 

In my WHMCS admin I can see BOTH the order AND the invoice being generated, but the customer is unable to pay because of this blank page.

 

In the list of orders I see, though, I see the order as having been placed but with "Payment Status" as "No Invoice due" (despite the invoice actually being generated!).

 

To complicate things even further, the customer attempts to pay again and again thus resulting in lots of duplicates.

 

To my knowledge, file permissions seem to be OK, what else should I check?

 

Thanks for your help.

Have you seen the error log of your server? Do you have action hooks?

Hi Kian, and thanks for replying!

 

The error log shows this:

 

Allowed memory size of 33554432 bytes exhausted (tried to allocate 130968 bytes) in /home/hosting/public_html/includes/dbfunctions.php on line 0

 

I'll Google for this error and also search here on the forum.

 

Meanwhile I have updated to 5.3.11 but the problem still stands.

 

What are action hooks by the way?

 

Thanks!

Hi,

Please increase your PHP memory_limit setting above 33.5MB. We recommend 64MB as a minimum:
