Ie enable all messages like for developing site, and you've got errors on page. After that enable php modules, which are required
I can't remember what modules I enabled after moving to 8.0. Because I have running wikimedia site too, and it also required some modules enabled. I'm fighting about 2 hours to fix all problems.
Found the next error in the System log,
is this caused by ZH Google maps or my template?
