I try to upgrade from 1.5.13 to 1.5.14 and i get blank page when i acces site.com/install (site.com/install/index.php?upgrade/)
I try with 1.5.15 and 1.5.15a version and the same problem.
I run on centos 7 with php 5.6
php -v

You will likely either need to disable Suhosin or adjust your Suhosin function blacklist. I'm guessing you have escapeshellarg blacklist, which really shouldn't ever be disabled (it's a string manipulation function).

No, Suhosin is interfering with code that has been around for a while. It's only triggered with upgrades though.

Note that it's specifically related to how the Suhosin function blacklist is configured.
