Safari 11.1 blocking Java/changing preferences doesn't work
I utilize a database for work that runs on Java. In the past with Apple updates I have been able to alter the security or website preferences in Safari to allow Java to run and turn off "run in safe mode". I also turn off pop-up blockers and clear the history/cache/cookies and reopen a new Safari browser. Up until this latest update this has worked. Now I have people at work who have updated and are running High Sierra with Safari 11.1 and these changes are no longer working. Java is being blocked. I have also checked the Java console to make sure the settings there are correct and the exception site list is correct. I am not getting any sort of error message. Is there a different method to stop Java from being blocked in Safari 11.1?
Mac mini, macOS High Sierra (10.13.4)
