Error while creating an article

Hi, I've come across this error while making my app and despite much googling was unable to find a solution for it. Could anyone help me out with it?

My setup is Python 3.4 django-cms==3.3.0 aldryn-apphooks-config==0.2.7 aldryn-boilerplates==0.7.4 aldryn-categories==1.0.3 aldryn-common==1.0.3 aldryn-newsblog==1.2.2 aldryn-people==1.2.1 aldryn-reversion==1.0.9 aldryn-translation-tools==0.2.1 django-reversion==1.10.2 django-sortedm2m==1.3.0

[shannon-rodricks]

So apparently I didnt google enough. Its a known bug in sortedm2m version 1.3.0. Reverting to version 1.2.2 resolved it

Thanks for reporting this, @shanrod220. We'll monitor the situation with sortedm2m and if another version isn't released soon, we'll pin the dependence to the earlier version.

For reference, we have an issue reported to the sortedm2m project here: https://github.com/gregmuellegger/django-sortedm2m/issues/80
