I understand from a conversation on #twiki that this is a bug in the upgrade script and that sylvieg is working on fixing it.
After upgrading from Tikiwiki 1.8.6 to 1.9.2 using the provided upgrade script, we experienced some weirdness with themes/logins after switching to a different theme, Codex.css:
- Selecting a link from the Recently Visited module caused the theme selection to revert to the theme that had been selected in 1.8.6 when the upgrade occurred.
- Selecting a link from the Bookmarks module caused the theme selection to revert and the user to be logged off.
- The new theme selection was not applied to group Anonymous, but would switch to the selected theme upon logging in.
Issues 1 and 2 went away spontaneously a couple of hours after the theme switch, but issue 3 has persisted.
4. A lingering issue is what to do to cure issue 3, as we have added content since issues began. Will we be able to simply rerun the upgrade script to fix the issue or will we need a patch?
