Interesting.. I too had this issue, however, I was able to overcome it by using http://localhost:8080 rather than the FQDN of the server; IE9 Win08 Srvr.

I am having this issue with build 1.434 on CentOS jdk1.6.0_18-b07 amd64 not running under tomcat, not winstone.

I have same problem on Jenkins ver. 1.442 on windows and winstone.
It appears after upgrading to 1.442 from 1.441 and downgrade won't help.

i get the same issue

Chrome reports an error here
function registerValidator(e) {
e.targetElement = findFollowingTR(e, "validation-error-area").firstChild.nextSibling;
e.targetUrl = function()

;
var method = e.getAt

Workaround is to backup a config files, reinstall jenkins, install all plugins and restore everything from backup.
Loading full backup is not working for me.

This is with the latest release, it is really slowing me up.

Addition to this, i think its actually a particular plugin that is causing the issue!!

This may the same issue as JENKINS-11053 (slave-setup plugin borks entire system).

I found this problem as well, at first I thought it was because I installed the following plugin: https://wiki.jenkins-ci.org/display/JENKINS/Create+Job+Advanced+Plugin

But it was because I had a ' character in my job's name.

Encountered the same today. Should be possible to fix ...

This is a browser related issue, not a plugin issue. This happens with current Chrome on OS X but not with Safari.

On Chrome I can see this on JS console:

Uncaught TypeError: Object [object HTMLTableCellElement] has no method 'hasClassName' prototype.js:856

I was able to replicate this with Jenkins 1.499. The issue was the clearcase plugin, which broke the setup when upgrading from version 1.3.13 to 1.3.6.
For me it was not browser related, since I could replicate on chrome/firefox/safari. Only when I dowgraded this plugin again, it was resolved.

I have the same issue, however it seems to occure at random.
I’m on Win7x64, Jenkins master on a remote Linux, using Firefox. I ssh-tunnel a port to the jenkins master, so I actually access it via localhost.

I had the issue months ago when we first set up our system. The issue seemingly got fixed once I set the Jenkins base URL to the one I used.
Just now I used Jenkins again, updating it and checking configurations etc, thus/then noticing the seemingly incomplete loading again.
The frequency of it occuring seems to depend on the job I try to configure.
Repeatedly hitting F5 for refreshing the page it occasionaly loads just fine.

The HTTP requests seem to return 200 OK just fine.
Just now, on one job configuration page I got the following JS errors:

I am seeing this problem with 1.527, upgrading to 1.528 did not fix.

No errors seen in logs when job configure page stalls with "LOADING" visible on greyed out screen.
Happens on all jobs.

No config changes were made within a day prior of this problem starting.

I also am seeing this problem in 1.528. I cannot seem to configure any of my jenkins jobs. I also am seeing no log errors or warnings when I attempt to configure a job.

I should also note that if I install jenkins 1.528 fresh, I do not have this problem. It only happens on our production server (d'oh!). The main differences between our production server and our fresh one is that one has lots of plugins installed and jobs defined, and one does not. I suspect this is a conflict with a plugin.

Because a saw 2 times some ssh publishing stuff displayed on the screen it tried to disable the ssh publishing plugin after a restart I can edit configuration again.

I'm using 1.528,I simply disabled "Publish Over SSH Plugin" and everything works fine , now.

For me everything worked fine until I upgraded from 1.524 to 1.528. Then I read this post and discovered that something is wrong with 1.528 so i downgraded back to 1.524 and everything started working fine again.
Seems some bug got introduced in 1.528. Need a fix.

https://issues.jenkins-ci.org/browse/JENKINS-19248

In my case it was also "Publish Over SSH Plugin" plugin.
I uninstall that and everything worked well.

https://issues.jenkins-ci.org/browse/JENKINS-19562
Disabled "Publish Over SSH Plugin" fixed the issue.
Yet we still require the plugin.

Believed to have been resolved with the fix in JENKINS-19457.

We solved this by touching the jenkins war file, to restart/recreate internal server directories (I guess).

We got this problem when moving an installation between machines. We figured it out when some of the javascripts could not be found. Looking at the webconsole (firefox) and the network we found that bind.js got a 404. The request was: /adjuncts/61a88662/org/kohsuke/stapler/bind.js. Touching the war-file and thus restarting jenkins another directory (simular to 61a88662) was used and then all started working.
