    v10: MediaIndexPopulator exception

    Version 10.0.0

    On a newly upgraded db and with a clean TEMP folder, I get the following after an otherwise clean startup/login and clicking on the first content node.

    Some hint on where to start searching for bad data appreciated.

    Same thing here, anybody found a solution?

    Basically we are unable to rebuild the interneal and externak indexes. This is one of the errors we encountered.

    Umbraco 10.4.0.

    Did you sorted out your issues?
