strpos() expects parameter 1 to be string

(@nathanrosen)

Since manually upgrading to 4.5.2, I can’t access wp-admin and I’m getting the following errors:

Warning: strpos() expects parameter 1 to be string, object given in /home/public/microhorror/wp-includes/functions.php on line 4003

Warning: Cannot modify header information - headers already sent by (output started at /home/public/microhorror/wp-includes/functions.php:4003) in /home/public/microhorror/wp-login.php on line 390

Warning: Cannot modify header information - headers already sent by (output started at /home/public/microhorror/wp-includes/functions.php:4003) in /home/public/microhorror/wp-login.php on line 403

Obviously there’s an error on line 4003 of functions.php, but I can’t figure out what it is. Help?

Have you tried:
-deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
-switching to the default theme to rule out any theme-specific problems.

I can’t do that; I can’t get to the dashboard.

I deactivated all plugins before upgrading.

Sorry, you don’t have to get to the dashboard. Using ftp or the file manager provided by your host rename the plugins folder plugins-old.

Rename /wp-content/themes/Workality-Premium-master to /wp-content/themes/Workality-Premium-master-old.

That should force WordPress to open with a default theme.

Still not working, I’m afraid.

After trying to disable the theme and plugins and it’s still not working, try reinstalling the core files then.

You can use this guide for reference: https://codex.wordpress.org/Upgrading_WordPress#Manual_Update

Still no good.
