Hello,
I have an error message constantly (hundreds of times the same message) in the logs/debug section. Can you tell me why and how to solve the problem? thanks in advance.

The message is : WARNING: Unknown: using touch command with binary protocol is not recommended with libmemcached versions below 1.0.18, please use ascii protocol or upgrade libmemcached in Unknown on line 0

That seems to be an server side warning releated to its configuration. Please contact your host about this.

Thank's for your answer. The problem is on my distant host.
