Time ago I wrote questions using LaTeX in HTML sections. Example:
\( \sqrt{{x}} \) which is: \ ( \sqrt{{x}} \ ) (without spaces)
I used it always. However, today I tried using them and in question preview the sqrt symbol doesn't appear
but rather the equation \ ( \sqrt{{x}} \ )
Recently I installed GENERICO filter. I think that is not the problem, but I think is necessary to mention it. In fact, I did the same installation in 2 sites, Only in one I have the problem so I guess I did something else.
Thanks
