Title: White Screen – 500 Internal Server Error Last modified: October 21, 2016 --- # White Screen – 500 Internal Server Error * Resolved [landauforte](https://wordpress.org/support/users/landauforte/) * (@landauforte) * [9 years, 11 months ago](https://wordpress.org/support/topic/white-screen-500-internal-server-error/) * Hi there * I’m working on a multisite setup and have installed and activated the Publish to Apple News plugin network wide. I have setup the plugin on one of our sites and it publishes to Apple News fine. I have setup the plugin with exactly the same settings on another site (same API details) but when I try to publish an article, I just get a white page in Safari and a 500 Internal Server Error on Chrome. * Apple have approved our channel, however I am currently waiting for them to approve our first article. * Does anyone know what may be causing the issue or where to begin with troubleshooting? Could the multisite setup be causing issues with API calls from multiple domains? * I’ve included the 7 error messages in the logs that seem to be related to a failed publish. (DOMAIN = I’ve taken out our domain identifiers) * Many thanks for your help, James * mod_fcgid: stderr: PHP Fatal error: Uncaught Error: Call to a member function can_be_anchor_target() on null in /var/www/vhosts/DOMAIN/httpdocs/DOMAIN/wp-content/ plugins/publish-to-apple-news/includes/apple-exporter/builders/class-components. php:448, referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) * mod_fcgid: stderr: Stack trace:, referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) * mod_fcgid: stderr: #0 /var/www/vhosts/DOMAIN/httpdocs/DOMAIN/wp-content/plugins/ publish-to-apple-news/includes/apple-exporter/builders/class-components.php(249): Apple_Exporter\\Builders\\Components->add_pullquote_if_needed(Array), referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) * mod_fcgid: stderr: #1 /var/www/vhosts/DOMAIN/httpdocs/DOMAIN/wp-content/plugins/ publish-to-apple-news/includes/apple-exporter/builders/class-components.php(25): Apple_Exporter\\Builders\\Components->split_into_components(), referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) * mod_fcgid: stderr: #2 /var/www/vhosts/DOMAIN/httpdocs/DOMAIN/wp-content/plugins/ publish-to-apple-news/includes/apple-exporter/builders/class-builder.php(45): Apple_Exporter\\Builders\\Components->build(), referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) * mod_fcgid: stderr: #3 /var/www/vhosts/DOMAIN/httpdocs/DOMAIN/wp-content/plugins/ publish-to-apple-news/includes/apple-exporter/class-exporter.php(186): Apple_Exporter\\ Builders\\Builder->to_array(), referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) * mod_fcgid: stderr: # in /var/www/vhosts/DOMAIN/httpdocs/DOMAIN/wp-content/plugins/ publish-to-apple-news/includes/apple-exporter/builders/class-components.php on line 448, referer: [http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push](http://DOMAIN/wp-admin/admin.php?page=apple_news_index&post_id=3798&action=apple_news_push) - This topic was modified 9 years, 11 months ago by [landauforte](https://wordpress.org/support/users/landauforte/). - This topic was modified 9 years, 11 months ago by [landauforte](https://wordpress.org/support/users/landauforte/).
