Description
When creating a new category within the "create posts" screen (post.php), there will be a javascript error. The new category will be created, but is only visible after refresh of the page.
It is a completely fresh installation of wordpress. Updated to 4.8.
Only default themes and plugins are activated.

Note:
See TracTickets
for help on using tickets.
There were additional lines after the closing php tag in an uploaded file in the plugin folder.
Therefore headers were already sent which results in this error!.
