I've installed v3.2.0 apparently successfully. When I login the screen simply returns back to the login page without any error. When I switch error logging on, I find the following:
edb.so' - /usr/lib/php/extensions/no-debug-non-zts-20090626/timezonedb.so: cannot open shared object file: No such file or directory in Unknown on line 0
My host is running PHP 5.3.15 on Apache 1.3.42.
