https://tools.wmflabs.org/erwin85/categorycount.php is marked red. What needs updating?

I just corrected the database names with sed -i 's/u_erwin85/s51362__erwin85/g' categorycount.php and now, having fixed T107618, it seems to work: https://tools.wmflabs.org/erwin85/categorycount.php?lang=it&family=wikipedia&namespaces=-1&category=Alchimisti&subcats=1&d=10&submit=Submit

catanalyzer.php seems to work as well, see correct output I just got:

I'm marking them blue. :)
