It's a change in Django 3.1 -> 3.2...

I am seeing this as well, just upgraded my application to Django 3.2.8 and seeing this on startup (runserver).

@jedie @valentijnscholten hope the PR #149 works for you guys as well?

[valentijnscholten]

Seems to work, thanks.

[jedie]

@nschlemm yes, this fixed the problem. When will it released?

[nschlemm]

@radiac can you chime in on the question of a possible release by @jedie ? thx :)

[valentijnscholten]

In the mean time you can install tagulous from git+https://github.com/nschlemm/django-tagulous.git@250b88c68507b39da7b5a88798e49805b94e81b8#egg=django-tagulous to get the fix.

[nschlemm]

@valentijnscholten while that is a workaround, I do much rather prefer we have an release to rely on - especially with the next updates regarding https://www.djangoproject.com/weblog/2021/dec/07/django-40-released/ already lining up ;)

[radiac]

Hi, have seen this and will merge and release asap, but I'm really pushed for time atm - please bear with me and I'll try to get it out in the next week or so.

[radiac]

Thanks for bearing with me! Released as 1.3.1.
