Articles Not Displaying

Since updating MODX, I can not view the individual articles created under the container. Even when right clicking and going to "manage articles." I can create them and view the web-pages, but when going to the container they do not show up.

These are the errors I get on my console

I uninstalled and removed all Article/related plugins and re-installed, this did not fix the issue. I navigated to assets/components/quip/connector.php and assets/components/articles/connector.php and verified they exist, I also changed permissions to 0755, and this did not help either.

If anyone can help me fix this it would be much appreciated. Thank you.

Did you update with the UpgradeMODX extra?

If not, try manually deleting all files in the core/cache directory and visiting the site with your browser in private or incognito mode.

If you did use UpgradeMODX, you can skip the first step.
