OOB Qualify button on Lead Isn't working

Hi,

The very strange thing is happening in my dynamics 365 organization,that all of sudden Buttons on the forms has stopped working.

On lead page the Qualify,Disqualify button isn't working. On Quote create Order button is not creating the Order.

Kindly suggest something. No customization has been done on Lead page.

Also I tried but it didn't help :-
