Mate, that's the lightweight style. Edit the CSS search for text-decoration: line-through; and change to something else or simply remove.

sorry.. but where is the CSS ? because i couldnt found "text-decoration: line-through" in the Edit template -> CSS Templates

thanks

You need to edit the lightweight.css file you would have uploaded to your forum root.

thanks..

works fine now :)

edit

how i can uninstall this ?

via product manager

Rock on... Works... 4.1.10
