Hi!

After upgrading netbox to 2.2.1 following the steps from readthedocs.io I get the following error and the pages won't load:
See attachment for screenshot.

<class 'django.template.exceptions.TemplateSyntaxError'>
Invalid filter: 'startswith'

It seems I may have screwed up something but sadly I have no experience with django/python so I do not know what I should look for, I was hoping you guys could help me out.

Thanks in advance!

I can't find any instance of that filter being used in the code base. Have you made any modifications to the code? And could you please provide a full stack trace of the error (you can set DEBUG=True in the configuration to get this).

:)

Indeed I had the title changed and found out a trailing <<<<<<HEAD in templates/_base.html
I fixed that and your awesome product is back online!

Thanks Jeremy for your very fast answer, and also thanks for your networking blog, you've taught me quite a few things!
