Maybe the title of the topic is a bit confusing, but I'll try to explain the situation: I've just activated my adsense account, and wrongly I entered the ads format as "text and image ads". After realising it was not what I wanted to insert, I changed in the ads options in my account to "only text ads" . The problem is that sometimes when I refresh there are "only text ads" but other times there is a text and image ad. I just wanted the "only text ads"... What can I do to solve this?
you can choose which type you want every time you are creating html code, if you change ad type in your account it won't change ads you have generated before. You need to generate a new code and put it on your site.
