Plank is not launching after tweaks
 

Hi,
I customized my desktop to look alike macos, except it didn't zoom and then I came across plank. But when I installed plank (installation was successful), plank doesn't launch. I installed plank preferences as well and when I try to run plank preferences, the following errors occur:

[WARN 21:11:48.519621] [Environment:161] XDG_SESSION_CLASS not set in this environment!
[CRITICAL 21:11:48.519687] [AbstractMain:257] Only X11 environments are supported.

Please help me out. I have been stuck for quite a while now.

Thank you.

would be nice to tell us a few words about your OS. Dropping in an error message is pointless.
