Edit the Portfolio Slugs
You can add your own portfolio and portfolio taxonomy (category, tag) slugs in two simple steps:
- Go to Portfolio > General section of the customizer and add your own slug in the appropriate fields.
- After changing your slugs, you need to update your permalinks, for this, go to your WordPress dashboard and click Settings > Permalinks, then just click the Save Changes button.
That's all, now you have custom slugs for your portfolio.
