refs #5406 make sure it shows an error message in dimension, do  not show an error if request was aborted and align the text left

refs #5406 added a more detailed error message, some ui tweaks and display a link to email sysadmin if possible

refs #5406 hide loading indicator if any error occurs and make sure to display an error message. Not sure yet about any side effects
