TECHNICAL SUPPORT / WEB APPs BUGS

Yesterday, I had noted that I had some problems on this forum.

I am wondering, what file should I delete from my /opt/ryzom directory to force an update?

I am NOT going to just delete anything randomly, for that would be a damn foolish thing to do, but can any one tell me what file would force an update.

PS: I use Linux (Debian Stable), the installation is in /opt/ryzom, and I use the most recent kervala client.

Thank you for any help that you can give me.
