ok, that "see more" thing is oxwall bug
they truncate comment without checking anything
so as result truncated comment could be truncated in the middle of a link tag
which depending on browser then can produce all sorts of weird things and this function is implemented as smarty modifier, so it is very deep level which cannot be overtaken
the only way to fix it is to fix that function to make it smarter
I guess this must be reported to oxwall so they truncate by default comments which are more than 150 symbols. My suggestion would be to truncate only if that is 150 symbols after tags are stripped. Or show that truncated comment when tags are stripped
that would be the easiest solution
