Portfolio pages disappeared. We're guessing this happened after an upgrade

We are getting a page not found on our portfolio detail pages. The list is shown with the image on the main page, but the detail page links are broken.
Here’s the link to our portfolio (case studies) page: conradlabs.com/case-studies/

The original link to the detail page was something like:

Now it’s showing up as:
These are both throwing a Page Not Found now.

We were able to find a cached version on Archive.org; the latest version is from March, 2019. web.archive.org/web/20190128105857/http://www.conradlabs.com/portfolio-item/case-study-wisegate/

We tried looking in the release notes for the last few months, but didn’t find any references to any recommended changes to how portfolios are handled in Theme X. Please help.

Hey @CLTeam,

That looks like a permalinks issue. Our theme could not break WordPress’ permalink structure so it’s possible that there’s a third-party plugin or a custom code that caused that.

Please first try resetting your htaccess file by renaming it to .htaccess-old. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button. That will make WordPress generate the default htaccess file which powers the permalinks.

If permalinks reset doesn’t work, please try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

If those doesn’t work, please keep all third-party plugins deactivated and give us your site’s WordPress Login URL, Username and Password in a Secure Note


Thank you! Updating the Cornerstone plugin resolved the issue and the portfolio menu item resurfaced in our WP admin console.

Hi @CLTeam,

Please remember to clear all caches when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors or any unexpected display issue on the site.

Glad to hear it’s sorted.
