[Bug / Issue] vbulletin 5.4.1 - unable to `post reply`

[klaasmidhold]

after the upgrade to vbulletin 5.4.1 i get an error message when i respond to a topic:
`Notice: Undefined index: contenttypeid in .../vb/library/content.php on line 4045 Notice: Undefined index: contenttypeid in .../vb/library/content.php on line 4046`

i did test it with the plugins off, and in the default theme
running on php 7.1, mysql 5.7

This isn't an error message. It is a "Notice" and shouldn't actually interfere with the operation of the software.

Please set display_errors to Off in your php.ini file. display_errors should always be off on a production server.
