It took me literally 3 hours to figure this one out.
I created some courseware using phprunner as the content editor. On the pages I am getting my content from WORD and pasting them into a ckeditor field in the add / edit page.
I am taking the text through notepad first to remove any formatting and have even switched ckeditor to source view when pasting the content in.
If the content has the word "from" or "select" in it I will get an internal server error.
the weirder thing is that one page will not allow the word "select" and the other page will not allow the word "from"
It's like there is something else in the page that is causing these to act like commands when I try to save the content.
