I updated to the latest Plex Server 1.27 ( 1.27.0.5849-99e933842 )and the libraries were gone when starting.  Checked for permission issues but that wasn't the case.   The log files are now filled with (libc++ errors?) these messages whenever a transaction occurs: got exception from request handler: std::bad_cast   I reverted back to Plex Server 1.26 ( PlexMediaServer-1.26.0.5715-8cf78dab ) and the issue disappears.  Same filesystem, same plex database.   examp
