Had 3.8.2, upgraded to 3.9.
Now getting all blank pages and this in my error log.
Fatal error: Call to undefined function wp_normalize_path() in C:\_APPLICATION\USCWEB\wp-includes\plugin.php on line 655
Stack trace shows this as the last call: wp_register_plugin_realpath() C:\_APPLICATION\USCWEB\wp-settings.php:213
Not sure what the issue is. Both of the files listed above are the updated version. Anyone else having this issue?
