Paypal ipn_main_handler.php?type=ec Blank Page

Ive been searching and looking for solutions for hours and still cant find why my http://www.anotherroundgolfclubs.com/ipn_main_handler.php?type=ec is blank! I enables CURL with hostgator like I was supposed to, but still nothing.

And yes, ive used the search feature, no clear solution. I put in the API key and everything.

Can anybody help me?

What version of Zen Cart are you using?

You are presently using: v1.3.9e

Has your site been upgraded? When? From what version(s)?

Nope

What addons have you installed? When?

Easy Populate, Fed Ex, Add Customers from admin panel, Max Mind, etc ,etc. There has been many but 90% of them are not related to payment processing.

In what ways is your site customized or different from a brand new uncustomized install?

I installed a theme, thats pretty much it.

What PHP version?
What's in your myDebug-xxxxxxx.log files? https://www.zen-cart.com/tutorials/index.php?article=82

HostGator is using php 5 now I believe. I can change between php 4 and php 5 in the cpanel.

Which specific PHP version are you using?
Login to your Zen Cart admin, and click the "Version Info" link in the top right navigation bar.

Also, what's in the log files I mentioned?

Here it is: PHP Version 5.2.14

EDIT: I dont know where those log files are.

As per the article, they're in the /cache/ folder of your site, which you must access via FTP.

Ok, ill pull them up and then reply.

It doesnt have anything related to paypay as far as I can see. Ill look at all of them.

Your issue might not be a PayPal issue at all. Maybe you've got something else broken on your site, which is only manifesting when attempting to use PP.

Well, I saw you work on the other problems that had the same issue, is there anything in particular that solved it? Should I reupload the files, or what?

In most cases the problem was a result of missing or damaged files, and usually the exact cause of the problem was documented in the debug logs which I've asked you to share a couple times already.

Also why the **** is it so hard to upgrade zen cart compared to other php applications, omg. Zen Cart developers are really smart....

Ok, well one of the logs said, this is probably it:

and now I just found out that: http://www.anotherroundgolfclubs.com/index.php?main_page=checkout_shipping is not working either...... this sucks.

Bump. I really need to fix this soon.

Fortunately that's addressed in this Tutorial/FAQ article which can be found simply by searching the Tutorials/FAQs section for that error message: https://www.zen-cart.com/tutorials/index.php?article=87

If it's still a problem then I'd expect you'd be getting blank pages on every click to your storefront.

Again, if it's not happening anymore, then evidently you've fixed the problem either by putting the missing file onto your server or by turning off the link that you were clicking on to trigger it.

Well, the host gator support guy fixed it for me. Also, why can't zen cart just show the errors? I hate some of the ways zen cart does things.

Zen Cart can't "just show the errors" because that creates HUGE security problems. If you give away the error message details to hackers, they can do all kinds of havoc with your system. Plus, your bank will shut you down because your site poses security problems.

If you'd rather get hacked, you can always break the safeties and turn on the error messages and just live with the consequences. Just don't come crying to us when you get hacked.
