[Theme: Constructor] plugin problems

Hi
I′ve been using constructor for a long, long time, now, and I must say I enjoy it. But every now and then I have problems using plugins, especially when it relates to images or galleries, or placing codes on post publishing. On blog page it always displays correctly, but when i click to see the whole post, it show the code, instead of gallery… Or, when I add caption to image, it show correctly on blog page, but not on post page.
I′d love to hear from you. It′s been a problem that really nervs me, maybe not from theme, but one that might bring to changing theme, since i can′t solve it…
