Beer leaking out of keg

[Barkingdog]

I pressure tested my kegs before filling. Filled keg sealed and rechecked for leaks. Enjoyed good pours for 2 days then found 3 inches of beer in bottom of kegerator. Found beer leaking out of beer side post of keg. (Note first use new kegeerator conversion kit)
