I have upgrade 1.43 to 1.45 and I have tryed to make a database backup by putty ssh command mysqldump .
But I have error message: access denied when using LOCK TABLEs.
How to do for making backup ?
thanks
This is nothing to do with Coppermine. Ask your host what backup methods are available for you to use.
Thanks for your answer but I am my host: I use a dedicated server and no parameter has change. I can save other databases but no more coppermine one.
self-hosting is only recommended for very experienced server admins (if at all). As Nibbler suggested: this is not related to coppermine at all. I suggest reviewing the mysql documentation.
