What if you close and re-open the app?

I closed and re-opened Joplin: it's ok ! ouf !

thanks

Oui, c'est un problème principalement quand on vient juste d'importer certains fichiers. Je vais corriger le bug pour la prochaine version.

j'avais effectivement importé quelques notes d' Evernote récemment; bon courage pour corriger les bugs, merci encore,. malgré ce petit souçi, j'apprécie de plus en plus Joplin

bonne journée

hello
juste une question à propos des liens internet dans une note ( importés par copier-coller ):
pour moi ils ne sont pas actifs, cad. n'ouvrent pas la page web concernée par ce lien; est-ce normal ?
je suis sous ubuntu 20.04 et Joplin 1.3.15
voir PJ joplin-error-lien internet

I'm not sure I cannot replicate this. Providing the exact Markdown that was used might help.
