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).

You will likely either need to disable Suhosin or adjust your Suhosin function blacklist.

The forum work fine now (version 1.5.13) with Suhosin enable, the problem is when i try to upgrade.
They are change on version 1.5.14 and .1.5.15 that don`t work with Suhosin?

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.

I solve the problem.
1. disable Suhosin for my domain
2. run upgrade
3. enable Suhosin again for my domain.

Now all work fine and i run last version.
thk you @Mike
