Unable to edit/create user in Magento 1.8 admin panel

I have inspected the element and see below error.

prototype.js.pagespeed.jm.ix8Kb1Gh8H.js:516 Uncaught TypeError: Cannot read property 'get' of undefined
www.ekabyte.com/:788 Uncaught TypeError: Cannot set property 'value' of null

Do you have a page speed plugin enabled at all?

Could you try disabling that - and try the page again?

Also check Magento's default JS merging is located at System > Configuration > Developer > Javascript Settings and change that to No to see if that has any effect.

1. Page speed enabled 6 months back and there was no issue with this. It was working fine.  --Wil check disabling once.

2. Merge JavaScript Files was already in disable mode.

Okay,

Please disabled Page Speed and let us know.

I have disable the pagespeed and cleared entire cache and checked still same. now again ababled page speed.

Hi,

Leave it disabled and check the console log again for javacsript errors.

Whilst its enabled its hard to see if a problem file exists since the page speed plugin merges all the files.
