Redmine

Hi I am facing an error when clicking on Wiki module of the project. It shows server error .
FYI- I am using Bitnami ubuntu virtual machine and I have two plugins installed - Image clipboard Paste and redmine_mention_plugin. These plugins are working perfectly fine but after installing these two plugins I found that the Wiki module is not working and showing server error-
"Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.

If you are the Redmine administrator, check your log files for details about the error."

I checked the production logs. Please check the attached screenshot of production logs.
