The default behavior of Mscan is to Automatically Delete /tmp Files.
On Siteground hosting, the mysql socket data is stored in the /tmp folder.
If the admin does not remember to change this default setting before running Mscan, running Mscan results in crashing all the WordPress sites on the account until Siteground techs restore the data from an image.
Can this default behavior be changed in future releases?
Thanks for letting us know this about SiteGround hosting. Not sure why deleting tmp files would cause that to happen, that is unusual. For now uncheck the MScan option to delete tmp files and we will look into this further to see why that would happen.
That’s the plan. The second time it happened (on a new installation), I cringed as soon as I hit scan, remembering a second too late to change the default.
So, it is repeatable.
And I did confirm with Siteground support that this was how they set up their shared hosting accounts.
We will look into this further, but obviously you don’t want to use the MScan tmp files deletion feature since it causes problems on SiteGround hosting. 😉
