hi guys, I upgrade php 5 to php 7.0, then pavilion no longer works, uninstalling pavilion from modules, edit or reinstall shows the same message, and when you enter to website too, I change to default template and all works, so the problem is in pavilion, it works on php 7?, first error was line 761 and 765, the expecion now is Throwable instead Exception.

PHP Fatal error: ‘Function name must be a string’
