I am trying to add things to the sidebars in the theme Hyaline 1.05. It is apparently not widget ready and I would like to include adsense and a variety of other such items. I enter the Theme Editor, click Sidebars and I have tried numerous things in numerous places. The simplest thing I have tried was typing the word "TEST" in various places on the page under both "sidebar 1" and "sidebar 2" and nothing happened. I have tried contacting the theme's author to no avail. Can anyone provide me with some guidance, please?
Please keep in mind that, even though I do know html rather well, I am not a programmer and I do not know CSS.
Thank you in advance.
