How to Clear LOGS ?

[Eleusis]

Forum Search doesnt work...... how do you Clear the LOG Cache ? Its real embarrassing when you invite a Girl and the last girls conversation pops up......

Cant use this program at all if this doesnt work,,,,,,

do I have to do it manually each time ? WHY ? How to do it ?

The letters here are so bright I cant read them. They need to be darker. Thanks
