External Storage Support -> internal server error

NC 13.0.2
PHP 7.0
Debian Stretch

I migrated my Nextcloud to another machine using maintainance-mode, sql-dump und rsync keeping timestamp. Works well. I had on my old machine External Storage Support in use with smbclient.

accessing the plugin on my new machine gives me internal server error. May I “reset” the configuration of this plugin? I can only deactive, but can’t remove it entirely to do a fresh setup.

Any suggestions?

Thank you in advance

I know this is an old thread but did you manage to resolve this as I’m having pretty much the exact same issue?

I replaced the corresponding plugin-folder with one from the setup zip-file. Be sure to unistall/deactivate the external storage plugin before doing so.
