Dear list,
  Although I am able to successfully create a bug, I get a 400 bad
request error.

  When I use the responsive template (roundup version 2.1.0) and I try
to create a bug, I get the following message in the browser:

400 Bad Request

The URL in the browser is:
https://example.com/example/bug2?@ok_message=msg%202%20created%0Abug%202%20created&@template=item

The log shows:

127.0.0.1 - - [17/Apr/2023 20:48:57] "GET /example/bug HTTP/1.1" 200 -
127.0.0.1 - - [17/Apr/2023 20:49:10] "GET /example/bug?@template=item
HTTP/1.1" 200 -
127.0.0.1 - - [17/Apr/2023 20:50:06] "POST /example/bug HTTP/1.1" 302 -


Any ideas,
Dave
