Error CuteNews 1.50

Hello, I come here to report a mistake first'm Brazilian. Well I managed to install CuteNews on my website, but when I went to see it was not where I put for example: I put it in a box with pictures in the background when I sent my hosting all ugly he was all messed up. If you can not understand what I'm saying into my site and view: $matches[1]. My website is in php format, do not know if I put some in dreamweaver but is causing my site get all messy, and intereçante and when I'll press the button read, but it returns to normal.
Sincerely,
$matches[1].

Prior to read but it is in index.php:".handle_img_tag($matches[1].$matches[3], false)."

After you press the button but read:".handle_img_tag($matches[1].$matches[3], false)."
