Backup error message

It sounds to me like the plugin and your server are not playing well together since the server seems to be expecting something different than the plugin is trying to do. Here is the support forum for that plugin:

That error message shouldn’t actually be a problem as the plugin will just fall back to doing the database backup via PHP.

The maintenance mode error you mentioned shouldn’t be related to BackUpWordPress as the plugin doesn’t touch maintenance mode stuff.

So you agree it seems like it could be a server issue, Tom?

Have been looking into this a little more, I actually think it’s an issue in our plugin.

It looks like SET OPTION was deprecated in MySQL 5.1 and removed completely in MySQL 5.6 in preference of just SET.

I’ve opened a ticket on our Github repo here https://github.com/humanmade/backupwordpress/issues/676 and we’ll get it fixed for the next release. Thanks for reporting!

OK thats great, thanks Tom!

Is this still to be fixed, Tom? Currently using the latest version of the plugin and am getting the error on all my sites.

Thanks.
