When i try to open archive pages i get a 404 error

Probably you have to go to Permalinks > click "Save Permalinks" and refresh that archive page to see if it solved.

If not, then maybe you are using some plugin that caused the problem? deactivate all plugins and re-save permalinks and check that archive page again.
