Since yesterday i noticed the portfolio items (individual portfolios) won’t show in our clients website. Instead, it shows the ‘Page Not Found’ error. I’ve checked the portfolio’s in the CMS and saw that they are still present in the ‘portfolios’ section.
I tried to re-publish them but no result. It shows the same page error when clicking ‘view portfolio’ in the editor. Same result when i add and publish a new portfolio.
Might this be a database issue? I have the plugin WP-Optimize installed. I can’t find the cause.
