Migrate to Database MariaDB, Thumbnails Gone and Scraper wrong language.


i have two nvidia shields and running kodi v21. yesterday i added an advancedsettings.yml. this works well, all my data is now in a shared mariadb. 

but  first i lost all the thumbnails. 

i tried to remove the thumbnail forlder and rescrape the whole library. no success. 

when i use themoviddb.org scraper and change the language, is still get the wrong language. when i had a lokal database, i hade no problems. correct language and correct thumbnails. 

what are the way to handle this? i hope i can save my seen and unseen states. 

thank you for any advice.
