Sometimes the default portfolio archive page overrides the page you set to use /portfolio/ as the URL.

If this occurs, you will need to disable the portfolio archive page to be able to use the /portfolio/ URL.

You can do this by editing line 26 /wp-content/plugins/adios-addons/custom-posts/portfolio.php so it looks like the following:



'has_archive'   => false,


After disabling the portfolio archive page, we still need to flush the url-rewrite rules.

This can be done in the Settings > Permalinks page in Wordpress Dashboard by changing the permalinks setting to something else, and then changing it back to its original value.
