There is some little problem when i upgrading my old Joomla version to the new patch of Joomla 1.5.14. The problem is after i upgrade my Joomla version, everytime i use the default text editor of Joomla, and put left or right alignment to an image, it always pulling the text under the image. I can't make a left or right alignment on the image. So if you had the same problem like me, you can solve this bug by downloading a php code of tinymce editor. After downloading that zip file, extract it and rewrite the file on your host server or localhost. So then the problem is solved.
