Problems with 3.5.1 – want to downgrade

Hello,

I am having several problems with my site. The main problem is with the “upload media” button which looks like a camera and a music note. This button does not work at all since upgrading WP. This is very major since it hinders me from inserting images into my slider plugins. I was using TheTheFly’s slider but it stopped working after 3.5.1. Other sliders I have tried also don’t work for the same or similar reasons, the upload media button doesn’t work. Also I am unable to insert a link or go to text mode when creating a page/post.

This may not be an issue with WP but I have read several other stories where people have been having issues with WP upgrades affecting their sliders, particularly another person who was using the TheTheFly slider who had the exact same problems as I have.

This problem is very major since the slider is on my front page and is currently not working. This seems to be driving traffic away once they reach the site.

So what I want to do downgrade WP to the previous version to see if it fixes the problem. Does anyone have any recommendations on how to do this?

Thank you!
p.s. If you have had similar problems or know someone who has, and you found a fix without downgrading, please please let me know.
