I recently purchased and install WP-Script KingTube theme my old wp theme lack some feature so I am planning to switch my theme to Kingtube

Everything is working fine but sorting filters on the homepage make URL PARAMETERS like

/?filter=latest
/?filter=most-viewed
/?filter=longest
/?filter=popular

however, My OLD URLs are like
/latest
/most-liked
/most-viewed

and I want to keep the old URL structure, WP-SCRIPT support is pathetic and they don’t seems to care it’s been 15 days they are not responding.

Can anyone here please help me to fix this issue?

I guess there is some block in theme function.php file but I am not sure

can anyone please point me in the right direction exactly what and where to edit

I shall be highly thankful to him.

Thanks
