with testmysite.thinkwithgoogle.com i tested an old Joomla 1.5 website and i got really bad results. I managed to working on some points and it was succesfull. Now i have a few points open.
What could i do on this points? The Joomla is old and putting all js files into one or compressing css is destroying the site and its not working.
Is there any other way how could i work around this point?
Does anyone have any experince on this CSS and JS thing with Google testing Tool, that could give me some good advice on how to work with it?
