Title: Call to undefined function wp_get_current_user() Last modified: August 21, 2016 --- # Call to undefined function wp_get_current_user() * Resolved [Eddie](https://wordpress.org/support/users/eddie6671/) * (@eddie6671) * [13 years, 1 month ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_current_user-2/) * After updating to the latest BPS, on a multisite WP installation v. 3.5.1, admin pages immediately became unavailable, due to the following error: * PHP Fatal error: Call to undefined function wp_get_current_user() in /home/apache/ wordpress/wp-includes/capabilities.php on line 1451 * According to: [https://wordpress.org/support/topic/plugin-post-from-site-fatal-error-undefined-function](https://wordpress.org/support/topic/plugin-post-from-site-fatal-error-undefined-function) * when this happens it is because wp-includes/pluggable.php contains this function, but this file is not getting loaded until after the plugins are loaded. * I was able to fix the problem by adding: require_once(ABSPATH . ‘wp-includes/ pluggable.php’); * to /wp-content/plugins/bulletproof-security/bulletproof-security.php * as soon as I added that line admin pages became accessible again and the error is no longer triggered. * [http://wordpress.org/extend/plugins/bulletproof-security/](http://wordpress.org/extend/plugins/bulletproof-security/) Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [AITpro](https://wordpress.org/support/users/aitpro/) * (@aitpro) * [13 years, 1 month ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_current_user-2/#post-3669038) * Wierd. BPS does not use the wp_get_current_user() function. BPS does use the WordPress current_user_can() function to check user capabilities. * Try commenting out the line you added below with 2 forward slashes and let me know if the error occurs again. It may have just been a coincidence or maybe there is some other factor that is not obvious going on. // require_once(ABSPATH.‘ wp-includes/pluggable.php’); * Plugin Author [AITpro](https://wordpress.org/support/users/aitpro/) * (@aitpro) * [13 years, 1 month ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_current_user-2/#post-3669039) * Did you Network Activate BPS on your Network/Multisite installation? BPS should not be Network Activated and should only be activated on the Primary site for Network/Multisite. * Plugin Author [AITpro](https://wordpress.org/support/users/aitpro/) * (@aitpro) * [13 years, 1 month ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_current_user-2/#post-3669081) * Oops yeah wp_get_current_user() is in capabilities and not BPS. Spaced out for a sec. LOL. Apparently this is some odd random occurrence that happens only on Mulitsite and I do not see that anyone has ever figured out what actually causes it. I will add this as it would not hurt anything, but I will need to research it fully before adding it. Thanks. * Plugin Author [AITpro](https://wordpress.org/support/users/aitpro/) * (@aitpro) * [13 years, 1 month ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_current_user-2/#post-3669197) * This has been researched and tested and everything works perfectly. Thank you for pointing this out.
