Field gets disabled

In my lead module suddenly I can find that account_name field becomes disabled and cannot enter any value. I have written js script making .disable=false but still i get this error for few records. Can anybody had this isssue
SuiteCRM - version 7.8.2

Hi,

Can you please remove .disable=false?
then delete or rename cache folder and then do repair and rebuild.

Thanks,

I have commented and rebuild but still some records 's account_name field is not editabled.

Have you rename or deleted the cache folder?

Thanks i sorted out. Since the account_name is linked with account module it was not letting to create duplicate name.
Now it works fine
