Before upgrading to WP 3.4 (or better 3.4.1) please remember that Evolve is not working in debug mode, so no way to test any other plugin.
Just a long list of warning that will crash the site.
I guess it is the same with a lot of themes apart Twenty11 and Twenty10 (do not know why now there are 2 standard themes, one of them very ugly...).
Side note the access to the support forum for Evolve Free is really read only without paying.
Not acceptable. It should be free for bug and crash, although I guess 90% of the post are for modifications...
