I’m in the process of updating wordpress to the latest release.
I was very behind with updates so basically everything broke up – I even had to open a ticket with the hoster (aruba.it) to update MySQL – they were very kind and quick to answer and act. PHP was easier to update (it didn’t involve opening tickets :)) but it was too old for wordpress to work too.
Anyway, in the next days I will try to get the thing up and running as it was (theme, plugins, etc.) and the target will be re-enabling comments and restart blogging.
Edit: Comments should now be enabled on all posts, with reCAPCTHA.
