When I deployed Redmine_Banner in Bitnami Redmine, Internal Error (505) was displayed and became unusable.

I'm using Bitnami Redmine in Windows 7, but I got an Internal Error right after I started using Redmine_Bunner and I can't use Redmine anymore.I don't mind if Redmine_Bunner is not available, so could you tell me how to restore Redmine?

• Windows 7 (32-bit)
• Bitnami Redmine 3.4.4.stable

I wrote it in the following entry.
I wanted to deploy RedmineBanner in Bitnami Redmine - Qiita

When I accessed localhost/Redmine, the top page was not displayed and the following error message was displayed with the title "Redmine 500 error".
