The first error is due to the index "title" not existing in the array which since you're now using strict raises a warning, you'll need to encase the entire thing into a condition based on whether the title index exists (you can use isset() or in_array() ) and after that whether a title object could be made. Strict enforces safe coding practice which can be a bit tedious and verbose, but it solid and predictable.

The second error is that you've tried to access $wgOut before it's properly initialised - you should be accessing it from the callback function registered with the OutputPageBeforeHTML hook.

You should really be executing the condition in the extension setup function or the class constructor not in the global scope (also the global keyword is redundant since you're already in global scope there). Also there doesn't appear to be any such function as egImageHistoryClear which you've assigned to the hook. --nad 19:50, 24 October 2008 (NZDT)
