Hello @squallss4,
We suggest that you navigate to WP-Dashboard >> Settings >> Permalinks >> set Post name type instead of the Plain type, save changes and try again after clearing the browser cache.
If the issue persists, please read and follow the instructions written in this article – https://elementor.com/help/how-to-fix-404-page-or-page-not-found-error-messages/.
Alternatively, please take a complete backup of your site and share your site WP Admin URL and credentials, as well as the FTP Login details, in the private content area of this topic. This will allow us to further investigate the issue and provide assistance.
Please note that we will need permission to debug your site, which may include deactivating all third-party plugins and on-site customizations.
Best Regards,
8Theme’s Team
