This is what I call the "Probatum" often written on the back of the will. It is almost always written in Latin (England stopped using Latin in legal records in 1733). I'll give you the transcription and then the parts that I'm comfortable with a translation.

Transcription (based on my somewhat ignorant understanding of Latin but decent ability at reading early modern English)

Probatu[m] fuit humoi Testamenta[m] vicesimo sexto die mensis Septembris Anno Dm [Domini]

Translation (my best shot at it anyway)

Probate was made [humoi? Not sure but it’s clearly written] of the Will 26th day, month of September AD

1648 in St. Albans before magistrate John Browne Clerk in Education

Honorable magistrate surrogate Mr. Thomas Goad [legam?] Doctor [offilis] for and whole[?] Archdeacon

of Alban London Diocese Commissary made administration all and singular

good right creditors etc. Alice Ruth, widow, relict and executrix etc. juror

etc. presented I Nicholas Rolfe Notary Public 

It's all really common in probatums. It essentially says the date the will was proven (versus dated). It means the testator is dead whereas he or she is living when the will is dated. It indicates the court being the Archdeaconry of St. Albans (Hertfordshire), which was in the Diocese of London and who presides over the archdeaconry with someone acting in his behalf. It indicates that Alice Ruth was the widow and executrix of the will.

I hope this helps.
