• 1 Your archive should be archive-vendorpost.php. – rudtek Commented Feb 20, 2022 at 5:29
• i using archive-vendorpost.php but not working – Lokesh8285 Commented Feb 21, 2022 at 6:42
• You should probably include the contents of archive-vendorpost.php as well as the problem may be that it isn't set up correctly. – Tony Djukic Commented Feb 27, 2022 at 5:28

1 Answer 1

If you are wanting to see the archive of you custom posts the archive will be:

archive-vendorpost.php

When you switch to a category there is a separate template wordpress uses:

taxonomy-vendorpost_category.php

Remember also, that you'll need to visit the permalinks page to reset them after as your code doesn't do that for you.

I've tested your code on my system and everything is working properly for me.
