[Koha] report behaves differently if run from intranet or the outside

[Alvaro Cornejo]

Hi

It seems to be a problem with the public setup of the report. Hard limit
somewhere in the code?

I changed almost all my reports to public to test and in all cases, I get
no more than the first 10 records.

I initially thought something crashed on the process but json files are
completed, not corrupted or damaged.

Regards

Alvaro
