Issue WordPress - Broken instance on domain

[HoracioS]

Hello, I'm experiencing problems with a Wordpress site. The home shows nothing and I can only see this on error log:

[Tue Dec 05 13:35:28.393431 2017] [fcgid:warn] [pid 30513:tid 140352015038208] [client 190.115.219.18:33861] mod_fcgid: stderr: PHP Fatal error: Cannot redeclare get_shortcut_link() (previously declared in /var/www/vhosts/xxxx.com.ar/httpdocs/es/wp-includes/link-template.php:2906) in /var/www/vhosts/xxxx.com.ar/httpdocs/es/wp-includes/deprecated.php on line 3899

Please help.

Best regards,
Horacio

It seems that your Wordpress contains an error. This does not look like a Plesk error. Maybe it helps to temporarily remove deprecated.php from the file system, but only guessing.

Removing deprecated.php not help...

Maybe one of the plugins is the cause of the problem. Try to disable all plugins and let me know
it helped or not.

 

[HoracioS]

Nope, doesn't help rename plugins

Download Wordpress from worpress.org and upload it to the server replacing the files. This should help.

What are you doing before it happened if I can ask?

The suggestion by @Tomek is the first step to take.

However, you should just login into the WP Panel and re-install the WordPress package from there: just go to "Dashboard > Updates > Re-install now (button click)".

First save a backup of the domain, before doing so. A small tip: create a separate mysql dump of the database AND save the wp-config file separately (to keep customizations).

That should be all there is to it.

Hope it helps.
