Plugin could not be activated because it triggered a fatal error

Ive developed my own WordPress plugin and it works great on any local machine, When i upload it to servers it wont activate.
Ive tried reinstalling WordPress. Using the default themes, Disabling all plugins.
All themes and plugins work except mine

I get the below error.
