The cache is not located at the coordinates above.

Consider the picture below.
Which predecessor contains a result that makes sense?

If you have found the result remove spaces and other symbols in such a way that only characters and digits remain.
Suppose A=1, B=2, ..., Y=25=7, Z=26=8.
Each digit keeps its value.
Let P(i) be the character or digit at position i, where i = 1, ..., # characters / digits.
Convert each character to one digit first.

The cache can be found at :

N52 ((P(1)-P(14))(P(10)).(P(3)-P(11))(P(4)+P(8))(P(9)))

E004 ((P(7))(P(5)+P(9)).(P(15))(P(12)+P(9))(P(6)-P(9)))

Good luck!
