Hello @burnuser,
Thanks for reporting this. You’ve hit a potential critical bug in 6.9 Beta 1 where a duplicated and modified Pages Template incorrectly overrides the original, default Pages Template sitewide.
This is likely due to an issue with template resolution priority or internal naming/slug conflicts in the new “Duplicate” feature when saving the template.Immediate Action & Workaround
- Delete the Duplicate: Go to Appearance > Editor > Templates. Locate your duplicated, custom Pages Template and delete it. This should force WordPress to revert all pages to using the original, core Pages Template.
- Report the Bug: Please report this issue on the official WordPress Trac (or beta channel) immediately, detailing your steps (Duplicate -> Edit -> Save) and the version (6.9 Beta 1, Twenty Twenty-Five theme).
This is a key issue that needs to be resolved before the final release.
