Thread:Project:Support desk/Images not displaying/reply (9)

Hello, I managed to upgrade my wiki to the latest version supported, which is 1.19.20, but the old images are still not displayed. Furthermore, when uploading new test images I get the warning messages:

▪	Could not delete lock file for "mwstore://local-backend/local-public/f/f8". ▪	Could not delete lock file for "mwstore://local-backend/local-public/f/f8/Test1.jpg

Finally, in the thumbnail frame it appears the message "Error creating thumbnail: sh: /usr/bin/convert: No such file or directory". Any suggestion?
