Unable to load sitemap data. Response received: <br />
<b>Fatal error</b>: Call to a member function getUserName() on a non-object in <b>/home/spaladium.com/public_html/concrete/models/collection_version.php</b> on line <b>97</b><br />

There was "glitch" while editing one of pages. Now clicking on sitemap reproduces this.

Any ideas please ?

after commenting two lines that call ->getUserName() I managed to save that page.
Afterwards, I removed comments and it's all working.

Strange but only one page produces that error and there is no obvious reason why. Other parts of site are just fine.

nm ... now it's working :)

I've found this is because I have deleted user that was one of contributor or creator of pages. After I reentered him in database with its first given ID, everything works fine.
