Thank-you

Is there a chance that you have [Web_Viewer] db_path = set?

If so, go ahead and remove db_path = whatever and see if that resolves the issue.

Hello,

thank-you.
Unfortunately :

[Web_Viewer]
enabled = true

and no more.

I tried to delete meshcore_bot.db, it has been rebuilt again, but the error is still there.
The bot and the MQTT client run correctly, only the web interface fails.
I'm on Debian 13 on AMD64, installation made by .deb file

The log fragment :
