Hello @saurabhdeveloper,

Most likely there is a conflict with your other plugin or your theme.
Please try to deactivate all your plugins one by one and check the issue. Thus you will find out which plugin causes the error.
If it won’t help, try to switch temporarily to a standard WordPress theme.
Afterward, let us know about the result.
