Preview draft gives Internal Server Error

[mabdullahabid]

Everything works perfectly but previewing a draft gives an Internal Server Error.

Am I doing something wrong or is that functionality not built yet?

Hi @wulaaf, thanks for reaching out to us,

Could you please describe with more detail the process you are following to get that error?

[mabdullahabid]

Sure! I followed the instructions on the docs to install puput. Everything worked fine on localhost with ./manage.py runserver. However, when I moved it to a staging website where I use gunicorn to run django with nginx.

Publishing and viewing the page works fine, however, when I PREVIEW a draft or an edited post, I get the following errors:

• Blog page gives a Bad Request (400)
• Blog post page gives Internal server error (500)

I'm using Wagtail 2.4.

Hi @wulaaf, can you try with version that I released yesterday?

Hi @marctc, I have the same issue even with 1.0.4 (wagtail 2.4). When I click on Preview (for a post that was created not by the admin but by a user that is in groups Editors and Moderators) on production server from a page like /blog_admin/pages/16/edit/ i got 500

`Internal Server Error: /blog_admin/pages/16/edit/preview/
