I have the old problem that the WordPress editor overwrites my HTML code. For example, the editor inserts <p> and <br> tags where you don’t have them set.
The second problem is the editor doesn’t show the real source code. If I write some code in the editor, and update, and look afterwards at the source code in the front-end (e.g. with Firefox), it shows there are tags which I can’t see in the back-end editor.
To suppress the problem, I installed the TinyMCE A. Editor, but it doesn’t always work. Why must I have an external editor to change it? Can’t WordPress have it’s own solution for this little bug?
I wish that WordPress would have the option to switch the Editor ON or OFF, so the user can choose. Some kind of solution might be a supplement in functions.php, where you can add shortcodes; I think that is laborious, but could it be the real solution?
