[1] I'm still on mysql-5.5.39 Installed versions: 5.5.39(16:42:22 08/09/14)(community perl ssl - bindist -cluster -debug -embedded -extraengine -jemalloc -latin1 -max-idx-128 -minimal -profiling -selinux -static -static-libs -systemtap -tcmalloc -test) > * Have you copied files into MySQL's data directory that originated > from a different version of MySQL?

How are they configured? mysql -u webadmin -h localhost -p website_test < website1_20141014.sql The server is on 5.5.36. website1 is the database name of the live site, and website_test is the local development database. The server is a shared server, so I'm getting its vanilla configuration with no choice on the matter.

Right now the machine is locked up - no space left on the root partition for some obscure reason. I need to start clearing stuff out. Thanks for your help! -- Regards, Mick
