I am trying very hard to understand why the editor (atto and TinyMCE) are removing my code.
1/ I have added an iframe in html block which works. but every time I go in to edit it remove the whole frame.
2/ I have just created a page http://moodle.langstone-jun.portsmouth.sch.uk/course/index.php?categoryid=107 with some tables using the table editor in Atto, I did add width="100%" to the table to strech it out as Atoo has no ability to edit this. I go back in to add something to the table, and all my tables are removed.
3/ I embed a Youtube video and go to edit and the code is removed for that too. Guess its the same as 1 using iframes.
Why is this happening and how can I stop it? If I use plain texteditor i get my iFrames code fine but the Tables are still removed/
