Since 1-2 months i am not able to add new words to the custom dictionnary
I posted this bug Bug #211985 before 1 month but i dont have an answer yet. any idea ?
Thanks

Check your enchant and aspell configurations. You may be able to add to their dictionaries manually.

the file of aspell that has the custom dictionary is in a binary format i cant edit it

The "aspell" command may help here. Have you tried System Settings > Regional & Language > Spell Checking?

- i've add a word in systemsettings but when i write it is alwayes underlined.

- When i add a word in the custom dictionnary (right click on the word → add to dictionnary) the word is added the time that i run the application.
when i close the application and open it again, the word is underlined. So it works until close the application.

This is (unfortunately) due to bugs in the KDE Spell Checking framework then. Please report a bug at bugs.kde.org.

i dont have the problem anymore
