Hi guys!! 1.5 rocks!!

however, encountered some minor hiccup probably when upgrading from 1.3.9 to 1.5. Normally, when I edit the main page, instead of editing the files directly, I go to the admin portal -> tools -> define pages editor. It was working fine in 1.3.9, but now in 1.5, it's not showing the pages. I instead just see a white text box with no HTML code.... and above it, it shows the correct path and filename of the page I want to edit:

/home/domain/domain.com/html/online/includes/languages/english/html_includes/mytemplate/define_main_page.php

I checked permissions and they are correct. Any suggestions? For now I'm editing directly the files, but I prefer using the admin portal.

Thanks guys!!
