News changes doesn't show on website

[Reggie]

Hi,

I have strange problem with the News module. I can add news in the admin section. But it's not shown in in the website.
I tried clearing the cache, but still no change :s

Damn ... I fucked it up 

I copied the files from a newer version over the installation, ran upgrade.php .. and now the MenuManager doesn't work.And lots of other things .. anyone knows a solution ?

From what version to what version?  Did the upgrade run successfully?  What are some of the other things?

[Reggie]

Yeah the upgrade ran fine. I updated from 0.13 Canary to 1.0 Hawaï
I also can't edit my pages. I get the tabs, but below there's a php error:

Fatal error:  Call to a member function on a non-object in /home/netbits/domains/spartakontich.be/public_html/lib/classes/class.contentoperations.inc.php on line 644
