AJAX Fails in 5.2.1. Update

[susanfla2]

Recent research on the Site Maintenance bug that issues AJAX failure and Loopback failure that disabling plugins only causes the Site Maintenance percentages to fail further i.e., 61% to 57% after re-enabling plugins which did not cause any issues. Since AJAX is essential to the core, an attempt was also made to enable legacy AJAX features due to the update. This did not resolve the AJAX failure either. Also, noticed that some features such as site statistics for sales are not working. AJAX is essential to transaction processing systems features as well as the core. Haven't seen issues in testing transactions in test mode, yet. What tests can be run using (Admin-Ajax.php) to determine missing functionality?

Hi @susanfla2,

I'm afraid I'm not exactly sure what this is reporting. It seems that you are trying to fix a failed test you are seeing in the new Site Health tool. There are no tests in WordPress core that specifically mention AJAX, though.

For this, I recommend opening a ticket in the ​WordPress.org support forums, as this is better categorized as a support request.

You also mentioned an issue with your site statistics for sales. This is not something included in WordPress Core by default. You will need to reach out to the support team for whichever plugin you are using for that functionality.

Ajax is part of the core of WordPress i.e., admin-ajax.php. Your latest update (which I haven't installed yet) attempts to resolve the issue for Site Health.

What I am seeing is several issues some of which existed prior to 5.2.1 update in the code but I can't locate the code anymore in the back-end to resolve the problem. For example the following code is related to an old theme which put random links in accordion of the customize panel:

<script type="text/javascript">
var ajaxurl = "\/wp-admin\/admin-ajax.php",
	pagenow = 'customize';
</script>

The code exists in the admin-ajax.php for pagenow but doesn't remove the links: see image. There is a series of this types of customization the old theme put into the admin on updates.

I'm not sure what you mean. Have you tested the latest update and just have not installed it on your production server? Can you detail how you are sure it is broken in 5.2.1 if you have not updated yet?

Can you detail what those problems were? As far as I can tell, nothing was changed in 5.2.1 that affects AJAX calls. You can see a ​detailed list of changes in 5.2.1 here.

For example the following code is related to an old theme which put random links in accordion of the customize panel

The code snippet still is included in the page output when using the Customizer. I don't know what random links you are referring to. Which section of the Customizer?

Can you provide more specific details and maybe screenshots about what you are seeing, and detailed steps for someone to reproduce the issue? This still seems like a support request and not a problem with WordPress Core, though.

Desrosj:

I updated from t.2 to 5.2.1 and then determined what issues I had with the new Wordpress Core update. If the update doesn't work I roll backwards to determine the difference. That's how I can detail issues I see that are different.

As far as the next update for WordPress Core, you just released it this week. I updated to 5.2.1 last week. Your new update for WordPress Core 3.6.3 outlines the following fixes:

Don't worry about the accordian. It looks like its in the JS and I will figure it out eventually, hopefully without breaking it...
