>> “…usually a Connection Timeout error is caused by things of this nature: intermittent server connectivity issues, website or host server is being attacked by a larger than usual Brute Force attack, your php maximum memory limit is set too low – should be set to a minimum of 128M, a particular plugin is using up all of your website’s resources…”
I think I will leave the recommended settings just as they are and see whether and/or how often any “Connection Timeout” might happen again. The display of the suspected “Who’s Online” feature of that particular plugin while I happen to be at the Dashboard is certainly not mission-critical!
Many thanks.
