OK, so removing the folder+file from the addon_data and re-downloading via the addon throws this into the log:

EDIT 1:
Running the manual update of ratings after the previous debug log throws this:

EDIT2:
OK, here is the report from md5sum. A) is the file currently installed on libreelec (after removing manually and downloading via addon again), B) is the file directly downloaded from the link you gave me, to my windows machine.
A)
[\\192.168.1.98\Userdata\addon_data\script.light.imdb.ratings.update\php-binary\]
php-cgi 68049abc60409d6a71afdef9d6330a8e
B)

The same hash ....
PS: SSH into the machine for privileges on the binary (the binary is the one downloaded AFTER deleting the one you recommended):
