My WP install was fine until i just did an automatic prompted WP upgrade. All the plugins/themes were up to date before upgrading WP. The upgrade was "successful" and reported no problems. However:
1 - after upgrading ALL my pages have a massive code dump at the bottom that appears to show content of ALL my pages. even my dashboard page has this dump. this occurred exactly after upgrading WP ten minutes ago, the site was fine before that.
2 - after upgrading WP reports that i'm using a "nightly build" although i did not choose such an option. so i upgraded again to the latest version, it was "successful", and i get the same message to update because of using a nightly build.
i cannot find any mention of this, can anyone help please?
