THIS END POINT RESULTS TO 404 : /account/listings/page/2/ , WHILE THIS WORKS FINE : /account/listings/ . I GOT AROUND 60 LISTINGS FOR ONE VENDOR, THEY ARE NOT ABLE TO ACCESS THE SECOND PAGE.
Please try refreshing the permalinks in Settings > Permalinks. You can select any structure, for example Post name, and save the changes.
If the issue persists, please try switching to the Default structure. If it works with Default but not with Post name, this usually indicates a server-level issue. In this case, your hosting provider needs to ensure that custom URLs are supported on the server (for example, the mod_rewrite module should be enabled).
