I upgraded my machine yesterday, from ZCS 7.1.3 to 7.2.0. 32-bit version Debian 5 packages, running on Debian 6 as per the ubuquitous howto.
Everything went fine (I even have my daily stats back that were lost when upgrading the machine to Deb 6), except for one thing: the "Zimlets" panel in the administrative console is nonfunctional. No error messages, no nothing - when I click it, the item goes selected-grey; but nothing else happens.
Nothing untowards seems apparent in the logs at first sight; I can still deploy zimlets from the "Admin extensions" panel; and the zimlets I thus deploy show up in the user view and are functional.
There is one new thing in my upgrade: I enabled the memcached that was previously disabled.
Has anyone else seen this behaviour and, more importantly, is anyone aware of a fix?
