How to fix these issues

Remove duplicate or additional meta description tags
Try to reduce the number of used JavaScript files.
website url : shorturl.at/fhwxP

any one please

your short link is busted

i looked at your source code
doesnt look like u have dupe meta tags
having too many is subjective. looks fine to me. yours all have a purpose.
reduce js files is obvious what it means.
do you have to? probably not. run the site through gtmetrix and see if any are causing a big slow-down and then edit as necessary.
i would ignore all those errors and go on with business.
