Many issues

Since updating this theme, the page has been a mess. All the changes I made in CSS do not work any more, plugins like qtranslator and gallery slideshow are also not working. Whene diting the post I cant use bold letters, or the bquote option and so on and so on. When i do write soemething the following items appear </a

I ve asked and expert and they say the problem has been the update.

I don′t mind paying for this template but i urgently need these problems solved.
