Hi, I realize the Wait Lists extension is in pre-release, but wanted to see if there’s a fix for this because it’s so close to being perfect. When a user signs up for a wait list, the page comes up blank. However if you refresh the page in the browser several times, the homepage comes up correctly with the message “You have been successfully added to the Wait List for…”
On the backend, the user is signed up on the wait list–that works perfectly.
Thanks in advance!

Hi there,
Which version number of Event Espresso core are you running?
Do you have access to the servers error logs? A blank page would normally mean an error is being thrown on the page, as it works after you refresh the page a few times, I’m guessing your site is running out of memory then when a little more memory free’s up on fresh it works.
So if you check the error logs do you see any error being thrown around the same time that you are testing the waitlist function?

1. Version 4.9.49.p
2. Error log shows:

That’s not actually an error, it’s a warning and warnings do not cause a blank page.
Can you follow this guide to activate WP_DEBUG mode? You may be able to capture the error with WP_DEBUG_LOG:

Thanks. I followed the instructions you linked. However the error log file is not appearing. Any suggestions?

You can create a blank file in the wp-content directory, name it debug.log.

I created the log file, but nothing is being added to it…

Does anything get printed to the screen if you set WP_DEBUG_DISPLAY to true?

No, nothing yet. (Thanks do much by the way for helping with this!)

You could try bumping the memory limit by adding this right after where you set the WP_DEBUG constants:
define( 'WP_MEMORY_LIMIT', '256M' );

Here’s what I now get in the debug log:
[31-Oct-2017 00:54:07 UTC] The The “add_to_cart_fragments” hook uses out of date data structures and function is deprecated since version 3.2.1. Replace with woocommerce_add_to_cart_fragments.

That’s a notice from WooCommere and won’t be causing the problem.
Is that the only entry in the log?

The only entries I see in the log are:

Have you tested signing up to a waitlist since enabling the debug log option?
You need to trigger the error now that error logging is enabled.
Normally a whitescreen means a fatal error is being thrown, the above are notices, they don’t stop the page from loading at all so are unlikely to be related to the problem.

Yes, for example I tried signing up for a wait list a moment ago and this appears in the debug.log:
[31-Oct-2017 12:30:49 UTC] The The “add_to_cart_fragments” hook uses out of date data structures and function is deprecated since version 3.2.1. Replace with woocommerce_add_to_cart_fragments.

Have you tried bumping the memory limit? You could also try temporarily deactivating the plugin or theme to rule out whatever is throwing the notice, it’s probably not related to anything Event Espresso, but you’ll stop seeing that notice while you troubleshoot.

Yes, bumped up memory. Also have theme and all plugins disabled, except Learndash CMS and EventEspresso. Still seeing error though.

This may be a server configuration issue where the referrer URL isn’t correct. Is there a page on your site where we can check the wait list signup form?

Sure, you can send detail using this form:
https://eventespresso.com/send-login-details/
If we don’t need login details to view the site just add dummy details so the form can send.

Hi Nate,
Can you remove the Version 1.0.0.dev.069 from your site, then go to your account page and download Version 1.0.0.beta.070, then install that version?
