Anything with "Strict Standards" can be ignored. But you can get rid of them by replacing your files with these if they bug you:

This error:
Fatal error: Call to undefined method InventoryView::alchemy() in /home/enchante/public_html/classes/class_frontcontroller.php on line 100
I am guessing is because the alchemy mod has to replace some existing files and they might not have replaced correctly. I suggest downloading the alchemy mod files and trying to upload them to your site again (aka reinstall).
