It appears something’s erroring out in the middle of a team page.
Errors like this are logged. Check the error log on your server. If you can’t find the log, please contact your host.
Meantime, enable wp_debug and wp_debug_log and after an error, look at wp-content/debug.log to see if anything gets logged there. https://codex.wordpress.org/Debugging_in_WordPress
You can also try this: Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
If you cannot access wp-admin, there are other ways to deactivate plugins.
Enable the WP_debug AND check pages backend content. If page content are also not showing there then inspect the page and check the bug. Its a jQuery issue so may you need to update the plugin and theme.
It’s a 500 error, @cleancoded, so jQuery is probably not an issue.
