Well here is a quote from their own website:

"LIGS UNIVERSITY IS NOT ACCREDITED BY AN ACCREDITING AGENCY RECOGNIZED BY THE UNITED STATES SECRETARY OF EDUCATION"

Source: http://www.ligsuniversity.com/en/accreditation-and-partners

I don't think there is anymore to be said

LIGS University is one of the most popular diploma mills in Czech Republic, LIGS seats in Prague, London, also Hawai. Hawai is seat of approx 300 diploma mills across the world.

In Czech Republic only VSEM - University of Economics and Management, seats Narozni str. Prague, Nove Butovice is able to provide partly distance MBA learning in English.

MBA tuition on VSEM is cheap, EUR 3 700 / year, living costs too, in Czech Republic is very cheap studying in compare with Poland, Germany, Hungary.

VSEM is accredited in US, CHEA, ACBSP, VSEM has full national accredition for Master of Business degrees in Czech Republic, wich is valid across European Union.

VSFS cooperates with City University Seattle, they are able to provide application to USA university, you can study MBA at CUS in Prage also, but it is partly English, partly in Czech language.

UNYP and other universities Prague College, AAU, and others not fully accredited for eg. UNYP has acrredited only BSc degrees, not MBA, Prague College is fully unrecognized, it is some kind of fraud. AAU in this time does not exists, in the seat Letenstak str. is abandoned object.

UNYP's MBA program is accredited by IACBE. Not a major or super important accreditation, but it is an accreditation.

Didn't Katz run an EMBA out of Prague as well?

Judging from the Prague EMBA's social media presence, which died out in 2014, I'd say they phased this program out. From the Katz EMBA website, only Pittsburgh and São Paulo are available as options.
