If you don't know about Wapka.mobi, then read this post. I personally don't want to encourage you to do this, because the site admin is really hard working and while you are reading this post, at the same time maybe he is working on Wapka updates. :)

Anyway i am going to tell you how to remove those bottom and PC ads on your site created by Wapka.

Remove Bottom Ads

I know that you don't know that there is a really simple tag which allow you to remove bottom wapka ads forever.
Just put it at the bottom of your site.
<#--!-#>
Remove # sign from code then use it.

Remove PC Mode Ads

When you visit your site via PC, you will find ads at the right side of your site. You can remove them easily.
Just paste this code in Edit Site - Head Tag

<#style type="text/css">
.item-control {
display : none;
}
.item-control a, .item-action a {
text-decoration : none !important ;
}
.widget-item-control {
float : right;
}
.icon-action {
border-style : none !important ;
margin : 0 0 -5px 0.5em !important ;
}
@media handheld {
.BLOG_mobile_video_class {
display : inline;
}
.BLOG_video_class {
display : none;
}
<#/style>
Remove # from the code.
