Support » Plugin: Jetpack by » Fatal error when trying to make config changes

  • Resolved kainwolf


    I am now getting the following error message when trying to do certain Jetpack config updates. On some, like the page wp-admin/admin.php?page=jetpack&configure=monitor I get a blank page, otherwise I get the following error:

    Fatal error: Uncaught Error: Call to undefined function xml_parser_create() in /home/www/wp-includes/class-IXR.php:264 Stack trace: #0 /home/www/wp-content/plugins/jetpack/class.jetpack-ixr-client.php(57): IXR_Message->parse() #1 /home/www/wp-content/plugins/jetpack/class.jetpack-ixr-client.php(120): Jetpack_IXR_Client->query('system.multical...', Array) #2 /home/www/wp-content/plugins/jetpack/class.jetpack.php(5594): Jetpack_IXR_ClientMulticall->query() #3 /home/www/wp-includes/plugin.php(525): Jetpack::xmlrpc_async_call('') #4 /home/www/wp-includes/load.php(638): do_action('shutdown') #5 [internal function]: shutdown_action_hook() #6 {main} thrown in /home/www/wp-includes/class-IXR.php on line 264

    Is there anything that I am missing?

    This seems to be a server configuration error. Could you contact your hosting provider, and ask them to make sure php7.0-xml is installed, or a similar extension for your server’s installation of PHP?

    I hope this helps.

    Yes, that was it; thank you so much. I had just upgraded the server from Ubuntu 12.04 to 16.04, and of course PHP from 5 to 7, and as I suspected, missing dependencies.

    For anyone else with this problem:
    Also once that was installed, had to detach and re-attach the installation from my account.
