Call to CCEvents fails as relevant file is not included. Diff attached.
hmmm, I just downloaded the zip for 5.0.1 and the cc-config.php is from version 11181 which includes a fix for exactly that issue. I ran this new install without any problem.
It looks like the checkin previous had caused this error on nov. 11 at 4:17, but it was caught and the fix was checked in on nov. 12 at 4:07 and the 5.0.1 zip at sourceforge is dated 40 minutes later.
I'm marking this 'works for me' and 'closed' until further notice...
OK, I got my 5.0.1 from on http://code.creativecommons.org/svnroot/cchost/tags/5_0_1.
Sorry - thought that the Creative Commons codebase was canonical :-(
I'll use the Sourceforge zips in future.
ah, well it comes as no surprise to me that, given the pace at which the patch was applied that the fix was checked into the wrong branch. I'll will fix as soon as I'm done rebuilding my dev machine.
meanwhile, I strongly encourage you and others to use the 5.1 branch as that has 100s of bug fixes applied to the 5.0.1 branch.
