I have a working installation of Roundcube 0.2 that I've attempted to upgrade to 0.3. When I follow the upgrade instructions and run through the installer pages, I get the login page, log in and then get a 500 error. Sometimes, I can refresh and use Roundcube normally. Other times, I get more 500 errors. I've included the contents of the errors (5 different login attempts) file below. The log file indicates the login was successful. And I've done a fresh install to a different subdomain with a fresh database and saw the same issue. Does anybody have any ideas of why this fails?
