What exactly does it break on the dashboard? * I have not heard this issue before and cannot reproduce it. * Thread Starter [zomblogger](https://wordpress.org/support/users/zomblogger/) * (@zomblogger) * [9 years, 11 months ago](https://wordpress.org/support/topic/not-compatible-with-wordpress-452/#post-7491923) * RavanH, * Installed Plugins: * AddToAnyShareButtons Akismet Backup Google AdSense Google Tag Manager for WordPress Social Media Auto Publish * Installed Theme: Zombie Apocalypse * When I activate XML Sitemap & Google News feeds 4.7.1 after updating to WordPress 4.5.2, * I receive an “Internal Server Error 500” when trying to access the Dashboard: [http://zomblogger.com/wordpress/wp-admin/index.php](http://zomblogger.com/wordpress/wp-admin/index.php) * The actual website, [http://zomblogger.com](http://zomblogger.com), continues to function but because I can’t access the Dashboard, I have no administrative functionality and cannot create or edit content. * I have been using XML Sitemap & Google News feeds on previous WordPress versions for several months with no problems. This error occurred only after updating to WordPress 4.5.2. * Thank You, Jim * Thread Starter [zomblogger](https://wordpress.org/support/users/zomblogger/) * (@zomblogger) * [9 years, 11 months ago](https://wordpress.org/support/topic/not-compatible-with-wordpress-452/#post-7491924) * RavanH, * I forgot to mention that while I still have XML Sitemap & Google News feeds 4.7.1 installed, I have deactivated it due to the issues I had. Probably obvious, but I thought I should mention it. * Thanks, Jim * Plugin Author [Rolf Allard van Hagen](https://wordpress.org/support/users/ravanh/) * (@ravanh) * [9 years, 11 months ago](https://wordpress.org/support/topic/not-compatible-with-wordpress-452/#post-7491927) * Hi Jim thanks for the additional info! I’ll try to reproduce, installing these plugins and theme. * Do you have access to server error logs by any chance? An error 500 can mean anything but the logs might reveal where it came from… * Plugin Author [Rolf Allard van Hagen](https://wordpress.org/support/users/ravanh/) * (@ravanh) * [9 years, 10 months ago](https://wordpress.org/support/topic/not-compatible-with-wordpress-452/#post-7491985) * Hi again, still have not been able to reproduce the issue. * Which plugin is “Backup” exactly? There are many of them but none seems to be called simply “Backup”. And the “Google Tag Manager for WordPress”? There are several with similar names… * If you can provide links to their WordPress.org plugin pages I’ll be sure to install the same ones as you have. * [cyberma](https://wordpress.org/support/users/cyberma/) * (@cyberma) * [9 years, 10 months ago](https://wordpress.org/support/topic/not-compatible-with-wordpress-452/#post-7491992) * Hi Ravan * could you please check this error? * [http://www.linkinghouse.com/sitemap.xml](http://www.linkinghouse.com/sitemap.xml) * XML Parsing Error: XML or text declaration not at start of entity Location: [http://www.linkinghouse.com/sitemap.xml](http://www.linkinghouse.com/sitemap.xml) Line Number 2, Column 1: ^ * Thank you in advance!
