Problem in creating a backup copy of a MODx site under MAMP (mac)

I have exported the SQL backup of a MODx site from my ISP server and imported it in a local MODx copy running under MAMP on my mac (0.9.6.1p2 on both machines); everything worked and I can login to the manager and see/update all the docs, chunks and snippets. But when I try to open the local copy of the site from the browser I get a blank page, which corresponds to a " Call to undefined method ditto::parseOrderBy() in /Applications/MAMP/htdocs/modx/manager/includes/document.parser.class.inc.php(769) : eval()’d code on line 783" fatal error in the php logs


any hints?

Make sure your MAMP copy of Ditto (assets/snippets/Ditto) is the same version as the snippet in the Manager.

yep that worked, I should have tried it by myself before posting, but I had the forum already open in front of my eyes ...
