r-labs » Redmine Information

Hi,
Greetings.
I have recently installed redmine 3.4.5 on RHEL7 and we use Redmine information plugin.
First things first, Redmine Information is a great plugin and thank a million for that.

Coming to the issues, I am facing 2 issues,

1. After installing redmine_information plugin, I am unable to save any changes in "Configure" page under Administration --> Plugins --> Redmine information plugin --> Configure.

I want to check "Use Graphviz (dot)" and update the path to dot. As I click on Apply, it returns "Successful update" but the changes are never saved. The information page is all messed up and the icons for Rails information and Wiki Macros are extended and gives a bad impression.

2. When I click on Workflow and Settings, it returns an internal error for both of them while remaining options return the expected results.

Would you please help me with correct configurations.

The details of installation are as below:
