I am very sorry. You’ll have to enable WP_DEBUG and WP_DEBUG_LOG in your wp-config.php file ([https://codex.wordpress.org/WP_DEBUG](https://codex.wordpress.org/WP_DEBUG)) and then provide me with a copy of the error message found in your debug.log file. * There’s definitely something broken here but I’m really not sure what the issue is without your help to find the error message. * I’m very sorry about this but I promise I can write the mistake if you can provide me with an error message from your logs. * Thaks, * [rwpett](https://wordpress.org/support/users/rwpett/) * (@rwpett) * [8 years, 5 months ago](https://wordpress.org/support/topic/database-update-5/#post-9950874) * I set the debug and debug_log to true, tried to update the database and got the following error Error 500 – Internal server error An internal server error has occured!

I saw another report of the upgrader getting stuck and it turned it was that WP_CRON. Our background upgrader relies on WP_CRON to process upgrades that take a while (a minute or more) so it’s possible that your upgrade got 67% though and then halted because the remaining updates were never triggered. * You could enable WP Crontrol ([https://wordpress.org/plugins/wp-crontrol/](https://wordpress.org/plugins/wp-crontrol/)) to try to manually move the process forward * Look for the cron task “wp_llms_bg_updater_cron” and click the “Run” button on it if it’s scheduled and it says “now” next to the next run. * That should push it home! - This reply was modified 8 years, 5 months ago by [Thomas Patrick Levy](https://wordpress.org/support/users/thomasplevy/).
