Update post returns blank page after updating WordPress to 4.7. Post still updates but it’s irritating to see a blank after post update.

What’s the best way to debug this?

[Rupok]

Hi there,

Can you enable WP_DEBUG mode? You can do this by opening wp-config.php and adding
define( 'WP_DEBUG' , true ); just above /* That's all, stop editing! Happy blogging. */ For example:

define('WP_DEBUG', true);

/* That’s all, stop editing! Happy blogging. */`

When you revisit the page with the white screen, you should have some error output describing the issue in more detail.

I enabled debugging. Updated a page and saw the issue again but this time with these logs.

What may be causing this?

fatal error seems to be

Catchable fatal error: Object of class WP_Term could not be converted to string in /var/www/html/wp-includes/taxonomy.php on line 2285

Does this look WordPress core issue?

@since 4.7.0 Refactored to use WP_Term_Query, and to support any WP_Term_Query arguments.

Hi there,

Thanks for writing back. Would you please revert to the older version. As it’s just released, you might face some issue. It would be safe to update after some more days.

[Nilesh L]

I see a different error now.

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/wp-includes/functions.php:3996) in /var/www/html/wp-admin/post.php on line 197

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/wp-includes/functions.php:3996) in /var/www/html/wp-includes/pluggable.php on line 1174

What may be originating this?

[Nilesh L]

When I edit a page and attempt to see a preview, I get a blank page with this error.

This wordpress is a staging area inside a KVM/libvirt based kubernetes on fedora cluster. Let me setup a replica for you to access from outside. Will take me some time to enable stage access. Thanks.

Please let us know when ready 🙂 Thanks!

I do not mind it you accidentally destroy this staging site.

Hi there,

Would you mind providing the exact procedure to reproduce this issue? Video recording should be helpful. I’m adding and updating the post and I can’t see the white/blank page. Maybe I’m doing it differently.

I also checked the debug log and I don’t see any fatal error.

Thanks!
