Wordpress works fine.
But recently started the error after trying to create new post of page.
bject from empty value in /…./wp-admin/includes/post.php on line 641
Could you please advice what can be the reason of it?
Thanks in advanced! ]]>
If that does not resolve the issue, try switching to the Twenty Seventeen theme to rule-out a theme-specific issue (theme functions can interfere like plugins).
]]>tests with plugins I made the first step afternoticed this error. It is not plugins issue I checked.
The same version of theme I use at the same server at two more domains. And their this theme works fine and does not conflict with the same worrdpress version. So the issue with theme seams also wrong.
Do you have other advices for me please? ]]>
If there’s no difference under the Twenty Seventeen theme, try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and delete then replace your copies of everything on the server except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.
Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.
]]>I tried with the default theme and it did not helped.
I installed completly new wordpress and it started working fine.
Then after uploading my theme the error again appeared.
So it means the problem us in the theme and I will dig it with theme developers.
Thank you! ]]>
