I tried creating a form in a page - but the formatting is not working properly.
When I enter, for example:
Your name: <input name="submittername" type="text"/><br />
Your E-mail address: <input name="submitteremail" type="text" />
wordpress then modifies it to look like this when you view the page:
name:<br />
<input name="submittername" type="text"/>
Your E-mail address:<br />
<input name="submitteremail" type="text" />
It's putting in a br tag before each input tag, and not putting them in where I actually made line breaks.
Note that the code is not actually being altered - if I edit it again, I see the original code I wrote. It's just when it's rendered for viewing the page that I get the modified version.
Also, I'm not using the visual editor at all - it's disabled in my profile - so I don't imagine it could be at fault here.
