Not able to save Jenkins configuration on Jenkins version 2.346.2

Hi All,

I have been using Jenkins from long time, but after update to 2.346.2 I am not able to save the configurations.

I am trying to add email notification for which I ad adding the email id and other required details.
But the changes are not being applied.

On using the developers tool in chrome , I am able to see multiple errors like:

  • TypeError: Cannot read property ‘hasClassName’ of undefined behavior.js:119
  • TypeError: Cannot read property ‘next’ of undefined behavior.js:119
  • TypeError: Cannot read property ‘hasClassName’ of undefined behavior.js:119
  • TypeError: Cannot read property ‘makeInnerVisible’ of undefined behavior.js:119

Please find the attached reference

Those errors are usually a result of one or more plugins installed on your Jenkins controller that have not been updated to support the transition that Jenkins 2.277.1 made from HTML table tags to HTML div tags for layout.

A detailed set of instructions are available in

Thank yo so much, that helped , issue was with email extension plugin. I removed that and after that its working fine.
