Besides some warnings (when display_errors = true), my tests sites appear to work quite well after having disabled ini_set. Is your site completly broken, or just a few views are? Can you send some screenshots or give us more details? Specially to try to reproduce those errors in the current version and avoid them.

The ini_set, as is also widely used in other open source packages, is not supposed to be a blocker, so the most part of the features of your site should work.

Thanks.

Sorry my bad, it seems it doesnt really break it, but rather displays warnings. I should be fine if i hide warnings I guess, but I do not wanna do that.
