which JS file?

Hi,

please can you let me know which JS file does the ‘view as’ and ‘sort by’
also is it the same for the ‘renew’ function for ads?

(The reason I ask is we have been trying to improve the speed of pages, at some point we have managed to stop the ‘view as’ and ‘sort by’ working
and if you have more than one Ad to renew, it works, but still displays the page as if only the first one has renewed)

Thanks in advance

Tony
