What happened?

1. After upgrading and reinstalling Joomla 6.1.1, the update finished with:

Error on updating manifest cache: (type, element, folder, client) = (library, phpass, phpass, 0)

After correcting that issue, the same error occurred for:

Error on updating manifest cache: (plugin, eos, plg_quickicon_eos, 0)

Both core extensions had state = -1 in the #__extensions table. After changing state to 0 for both extensions, reinstalling Joomla 6.1.1 completed without any warnings or errors.

Version

6.1

Expected result

Reinstalling or updating Joomla should complete without errors. Core extensions should not cause updateManifestCaches() to fail because of an invalid state value in the #__extensions table.

Actual result

The update completed with warnings and errors:

Error on updating manifest cache:
(type, element, folder, client) = (library, phpass, phpass, 0)

After fixing that extension, the same error occurred for:

Error on updating manifest cache:
(type, element, folder, client) = (plugin, eos, plg_quickicon_eos, 0)

Both core extensions had state = -1 in the #__extensions table. After changing state to 0, the errors disappeared and reinstalling Joomla 6.1.1 completed successfully.
