Update to WP Core 4.5.3 Broke Access to Admin area of site

I just updated to WP Core 4.5.3 and no have no access to my Admin area at all. I cannot login. The site seems to function normally but I can't access it. I've attached screenshots of the error messages I've seen. Any help is much appreciated.

I am running the SEO Company Theme on Linux Cloud VPS from Liquid Web.

Many thanks.

    Hi Justin,

    Hope you're well?

    It looks like possibly an issue with your theme not working correctly with 4.5.3, or maybe a plugin conflict.

    Can you try the following using FTP, or your CPanel Filemanager.

    Navigate to /wp-content/

    Rename the /themes folder to themes-tmp
    Then create a new themes folder

    Now try & access the admin of your site, it should revert to a default theme. if you can get in admin, it would seem the theme will need updating to work with 4.5.3.

    Otherwise, if you still have the same issue.

    Do the same with the plugins folder, rename it & create a new plugins folder.

    Then try again and see if you can access wp-admin.

    If that then works we know it's a plugin.

    So now, copy each plugin folder from the renamed plugins-tmp folder, to the plugins folder you created 1 at a time, and test each time until the issue returns, then we should find out which plugin might be causing it.

    You can alsocheck your servers error logs tosee if any errors are showing up there too.

    Hope this helps
