I cant get my homepage to show changes I make, please help!
My homepage is only showing the cached version, and wont show any new categories I add or any new posts at all. I installed wp-super cache and quick cache in the past, but even when I uninstall them, I cant get rid of the cached homepage.
Please tell me what to do.
Thank You!

My website is http://vegaszine.com
I followed all those instructions, and I cleaned my browser cache, and loaded on diffrent computers, but still no change.

There has to be another way, please let me know what you think I can try.
I will gladly pay anyone who can fix this problem for me!!!

Below is what still shows on the source code of my homepage:
