the same with me
any advice

PS: I also could even not find an site ID.

Sorry for the delay.
1. I deactivated YOAST – and the problem was gone!!
2. I also deactivated all connected plugins; like AMP and AMP Yoast, as well as qtranslate-x & Yoast. – Again No Problem.
3. Then I activated the different way. qtranslate-x first, second Yoast and so on.
4. By activating Yoast the problem appears again!

My Problem is that I am also running a testserver (localhost) and there isn’t a problem.
By the way: on Posts and Pages backoffice the “Help” and “Screen Option” dropdown also doesn’t function (this proble also is gone when deactivating YOAST)

Here is a screenshot of the console:

Now I went down from PHP 7 to PHP 5.6 again and deleted W3 Total Cache, as well as other minifying tools. Mainly because my site went completely down.
Now everything works again, but not “Posts” and “Pages”, as described above. New is that I now have an error message when going to the page in admin area.

The page tells me the following:
Fatal error: Uncaught exception ‘Exception’ with message ‘Serialization of ‘Closure’ is not allowed’ in /html/wordpress/wp-includes/class-wp-query.php:1045 Stack trace: #0 /html/wordpress/wp-includes/class-wp-query.php(1045): serialize(Array) #1 /html/wordpress/wp-includes/class-wp-query.php(1670): WP_Query->parse_query() #2 /html/wordpress/wp-content/plugins/wordpress-seo/admin/links/class-link-columns.php(182): WP_Query->get_posts() #3 /html/wordpress/wp-content/plugins/wordpress-seo/admin/links/class-link-columns.php(172): WPSEO_Link_Columns->set_count_objects() #4 [internal function]: WPSEO_Link_Columns->count_objects(‘top’) #5 /html/wordpress/wp-includes/class-wp-hook.php(298): call_user_func_array(Array, Array) #6 /html/wordpress/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(”, Array) #7 /html/wordpress/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #8 /html/wordpress/wp-admin/includes/class-wp-posts-list-table.php(506): do_action(‘manage_posts_ex…’, ‘top’) #9 /html/wordpress/wp-admin/include in /html/wordpress/wp-includes/class-wp-query.php on line 1045

Can anyone help me out of this problem? OR any advice?
Yoast SEO Plugin just tells me that everything is fine.

So, right at the beginning. Nothing changed!
I have reinstalled WP, cleared out .htaccess and nothing changed – meaning the above error still exists.
I also turned on debug mode and these were the error messages:
____

} else {
$value = call_user_func_array( $the_[‘function’], array_slice( $args, 0, (int)$the_[‘accepted_args’] ) );
}

I am no programmer and not familiar with that code. It seems to be an error from qtranslate-X plugin, but I have no idea how to fix it.
Any advice?

Could you please explain your last sentence again in more detail, please. As reading this I remembered that my hosting provider changed the php version to 7. So maybe this is my problem.

first thanks for all your advice.
I checked wp-config, but nothing unexpected there. Only I should mention that I have W3 Total Cache installed, which wrote to wp-config and .httaccess.
I should also mention that every plugin and template worked fine; no updates, etc and suddenly I got the error.

When reinstalling WP via updates page. Will everything work again then or do I have to reinstall plugins like W3 Total Cache or similar ones?

I also temporarily changed the theme without any result. And, no there is no .htaccess in the wp-admin folder.

Again, thanks for your support and future support.

This can’t be the problem because I am running several sites. And only this site (on the same server) has this problem. Probably this is also the reason why I struggle.

I have the same question!
Can you please write some advice or thoughts on the future.
