Blank Paypal Page

What is the URL at the time of the blank page? Is it still on your site or has it already redirected to paypal.com at that point?

I can’t reproduce it myself and the client hasn’t said /doesn’t know. From what she said, however, and the steps she told she had followed it would appear that it has redirected to paypal. She did mention that in the top left corner of the page a small -1 appeared.
I am sorry I can’t be more specific.

Okay, yes we’ve seen that before. That means it has not made it to PayPal yet, and something is failing in WordPress. Generally the blank page with a -1 means that one of the standard WordPress functions was not able to run for some reason. This can happen for a number of reasons.

The first thing to check would be if you have any caching / CDN services running in WordPress or on the server directly. If so, get those cleared out and then re-save your payment gateway settings even if you don’t have to adjust anything.

If that doesn’t help there could be a plugin or theme conflict. The only way to troubleshoot that sort of thing is to temporarily disable other plugins and switch to a basic theme to see if the issue goes away. If so, then re-activate each one-by-one until the problem comes back to find the culprit.

Of course, it’s recommended to do that sort of testing on a separate test/staging site so that you don’t affect your live site. Your hosting provider can probably set one of these up for you if you don’t already have one.

Thanks for this. I’ll see what I can find. You’ve given me some good directions.

Well, I’m stumped. I’ve cleared caches but it happened again and then I set up a staging area. In there, I tested it and the blank page with the -1 showed up. Switched off the plugins and retested and it never came back.
I even tried using a VPN and could not recreate the issue.
I have no clue what to try next, but thanks for helping.
I’m writing this because the info might be useful for others having the same issue.

I’m confused. Are you saying it’s working now or that you’re still having problems?

The problem is that I can’t make it happen and I can’t figure out why it’s happening.
The Blank page problem appeared once and only once in the staging area when I had all the plugins working. Then I removed them all and slowly added them back in, using an incognito browser. I couldn’t make it appear again. That’s what’s got me stumped. It doesn’t appear to be something which happens in any predictable fashion or in any repeatable way.
As I said, I tried doing everything I could think of to get it to happen: incognito browser, VPN, different browsers…. and the only time it did it was the very first time I tested it in the staging area.
If I can’t reproduce it, I can’t fix it.
All I know is that it doesn’t happen to everyone who visits and that’s about as far as I can get.
So, yes it’s still a problem, but an erratic and occasional one which, so far, is not reproducible.

Unfortunately, I’m in the same boat you are. If we can’t reproduce the problem then we can’t fix it either. If you’re able to come up with any more information please let us know and we’ll be happy to dig into it more with you.
