Duplicate of #2054

The workaround is to set bleach<6 in your requirements.txt

The pull request #2059 has not yet been merged, but you could always fork the repo and apply it yourself if you really want to use bleach 6.0

Thank you so much I am excited there is a fix and i will have a site soon. But can you be more specific and explain what I now need to do like im ten?

[therealjohndion]

specifically, I am trying to figure it out on my own, but where is requirements.txt, and what command do i have to run to update (downgrade) the package bleach?

explain what I now need to do like im ten?

Likely the fastest/easiest solution for you would be to run pip install "Bleach<6".

The above advice is predicated on several assumptions about how you have things set up and how you have installed Mezzanine. If you are using a virtual environment, type which pip to be sure you are running the pip command associated with said environment.

Like everything in Python/Django/Mezzanine:

There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
