Multi-Domains Updates , After remove older version in the folder my plugins is gone

Dear Sir,

On my Dashboard show Multi-Domains Updates Available.
I click update and "go to Install Multi-Domains", then

Install multi domains on
mainsites.com update to 1.3,

Many time , then I see the

Multi-Domains Instructions

Other important notes:

As of Multi-Domains version 1.3, it is no longer necessary to manually install the plugin in the mu-

plugins folder. Woot! If you have an older version in that folder now, please remove it.
It is also no longer necessary to manually update the sunrise.php file as that is now done

automatically. :slight_smile:
Finally, if you are also using our Domain Mapping plugin, be sure that it is at least version 4.0.3.I

On the top of Multi-Domains Instructions
"If you have an older version in that folder now, please remove it."

Then I remove all my muiti Domains plugin file without backup.

Now I can not find any update multi domain plugins in Setting, and all my hundreds domains I added is gone!!!

Not update why ask remove it first at the instructions.
Where is the plugins and all my file?

Thanks!
