Description

After auto upgrade I got
Cannot redeclare class WP_Tax_Query in example/wp-includes/class-wp-tax-query.php on line 22

I have $wp_version = '4.2.9';

$ grep -r 'class WP_Tax_Query' *
wp-includes/taxonomy.php:class WP_Tax_Query {
wp-includes/class-wp-tax-query.php:class WP_Tax_Query {

It's with an old install. Just visited the page, it was 4.2.7 and had some other issues https://core.trac.wordpress.org/ticket/37236#comment:3

Attached patch fixed the issue.

class-wp-tax-query.php was added in WordPress 4.4, see [33760]. I checked out the 4.2 branch and downloaded the partial update package offered on https://api.wordpress.org/core/version-check/1.7/?version=4.2.7, none of which contained this file.

Are you sure you are running 4.2.x? Sounds rather like some corrupt files after doing an upgrade to 4.4 or 4.5.

Yes, looks like some corrupted files. It's an old blog (installed in 2009 :) that I visited and had some fatal error (Cannot redeclare class WP_Roles in /web/blog/wp-includes/class-wp-roles.php on line 26).
Fixed just to make WP run and it auto upgraded and then came the above mentioned error. Maybe it was 4.2.5 (had errors) then upgraded to 4.2.7 and then 4.2.9 :) Sorry, but really weird. As I mentioned an old blog with low traffic.

Yeap, running 4.2.9, check source at http://www.optimalizaciaseo.sk/blog/ http://i.imgur.com/hbZg1NY.jpg

What blow my mind were the files (wp-rss, wp-rss2) I saw after connecting to the FTP

The error log of my journey is at http://pastebin.com/v3TyF1qE (the WP_Roles error was there from 26th June 2016, I don't have older logs)

It sounds like you've had a failed update attempt to 4.4 or later, and then it's continued the autoupdates on the 4.2.x branch. Half your files are probably 4.4/4.5 and half 4.2.

You'll need to update WordPress to the latest release (at this point in time, that's 4.5.3). You can either do that through the Updates section of the Dashboard or manually by FTP.

If you continue to experience these problems after updating, please feel free to re-open this ticket. I'm marking as invalid for now.
