Error in JSON Data from admin-ajax.php

[baekerIT]

We've got a problem with our WooCommerce eShop:

It's not longer possible to get the Grid view functional.

In Webdeveloper i saw, that the JSON response from admin-ajax.php is incorrect and throws an Error.

WP-Debug, Plugins everything deactivated and activated again - the System is Windows Server 2012.

In List View, there are no problems - but my customer cannot use the Grid View to add Product Images e.g.

Hi,

sure, but the Bug is in the Media Library, not in WooCommerce.

When clicking the Media Overview, the round circle loads permanent.

I'll attach a screenshot for you.

How many product images do you have in the media library on that site. Also what is the memory limit defined as in wp-config.php?

There are 432 Entrys at the Moment, Memory Limit is not defined in wp-config - but it is set to 1 GB (WP System Health)

@baekerIT Does it still happen with all plugins disabled and a default theme activated?

[baekerIT]

@ocean90 I've to wait for the Serveradmin to create a development Database for testing.

Otherwise: This Problem appeared from one day to another. So I've just fount out that the Problem appeared, when the actual Childtheme is used. With the Parent Theme activated, the Media Library fully works. Thanks :)

Replying to baekerIT:

So I've just fount out that the Problem appeared, when the actual Childtheme is used.

@baekerIT Sounds like the child theme has a file with a ​byte order mark inserted. You can try to re-save all files as UTF-8 without BOM using Notepad++ or another editor. I'd start with functions.php.

@baekerIT Going to close this ticket again, since it sounds like you traced the cause to your child theme.
