Just starting yesterday, I cannot edit my template (under 'extensions' 'template manager'). Whenever I try to add CSS, change a menu, add Google Analytics code, or anything. I make my change then click save. The browser thinks for a minute then just redirects me to the main template menu. No changes are saved. I have tried several browsers and computers with no luck. I noticed today it is also effecting one of my modules (Perfect AJAX Popup Contact Form). The same thing happens with this module. Make a change, save, redirects me to the menu, nothing saved. I am at a complete loss.

This one is an even larger mystery. My site looks just fine, then sometime last night I checked it out and in the main body all my margins (or paddings) are gone. Everything is right up against the edges of the page and all top/bottom buffering is gone. This happens for everything on every page. I believe the margins that are being disabled are attached to the individual modules, not the page, but I am not sure. As part of this, the little Joomla edit links that show up on the page when you are logged in are also gone. SO, I randomly took my site offline, put it back online again and it went back to normal. Strange. Today, site looked fine, then out of no where I lost all my margins again. Took site offline, put it back online, and it was fine. As of right now, the site is fine (I know that is unhelpful to you), but I am certain it will kick the margins off again. I am totally baffled.
Sorry for the long post

ANY insights would be helpful! I have edits I need to make to the template that I cannot make and I would like my site to not look ugly due to a lack of whitespace.
