My site don´t saves the changes I make

Permalink
Well, i am new at concrete5 and I have some problems. 2 hours ago I made some changes on the pages and the sidebar of my site. When I went out of the admin account, my site was just like after I made the changes. I entered to my admin account and there were the changes and then I went and the changes disappeared :S I tried to Refresh my site but nothing. I lefted 1 hour and then I entendered and is the same.

What can be the problem?

Thank you :)

Try clearing and/or turning off your cache in the dashboard. You might need to clear you browser cache as well.

I usually turn the cache off the very first time I enter the site after installation and leave it off throughout development. When everything is done, then I turn the cache back on.

This is very basic but I must ask you. Did you Publish your changes ?

while in edit mode click on versions see if you have the current version approved.
