Question: I try to create a new module to put on the left side after the main menu with adsense code, i create it and put the code on the custom output content, but it appears the script code on the main page, what i have to do to appear right and not the code?
Answer: Go to your global configuration and Change your editor to No. After that go to Modules and press "new". Name your article, select placement and paste your code. Now it should work. You can also use the Banner client to make a new banner module or use one of the ready made modules Here
