Resolved Weird issue on one clients hosting page

[hostking]

When client logs in this is seen. Client was on websitepanel before. We upgraded the wordpress site there from 2.3.1 to the newest wordpress version.

When we move the site across to plesk now it gives the attached image error.
Any ideas? Site loads fine and wp-admin page is fine on 4.5 its just this error on plesk interface and load.php of wordpress does exist.

Hi hostking,

your previous manual upgrade wasn't complete. Consider to replace the file "...httpdocs\wp-includes\load.php" with the original wordpress - file from for example: => https://wordpress.org/download/release-archive/ ( pls. choose the CORRECT version, according to your current wordpress instance! ) and pls. make sure, that the file has got the correct permissions and owner rights.

Consider as well to correct possible wrong file permissions with the Plesk "Reconfigurator utility".

Seems to have fixed itself. Probably cron rechecked it.
