i replaced the templates code of a theme by another theme now it
become like this how can i remove it??
You want to Remove Icons ? Open newthread and newreply "templates" and search and remove {$posticons}
the icons are not appearing so how can i add it???
If you replaced the code with another theme's code, then it's probably looking for the icon in the other theme's folder, which does not exist.
Paste the contents of your newthread and newreply templates here.
Shift+F5 or Shift+refresh will do the trick. The smilies are showing up for me.
