Maybe there is someone who knows solution, thats my problem
without quote or code tag everyting is fine postbdy looks as it should

but while usng one of them its all messed up

is the way to fix it without having to remove postbody code ?

which part of that do you want to fix??

This part in second image, if you can see using quote (or basicly also code, or spoiler) tag cause damage to the postbody frame its visable on image #2
Its marked with the red squares.
