I have a main Site and a 4 sub-domains (independdant installations not multi-sites) and all were working ok before upgrading to 3.0.4. Even after upgrading the sub-domain sites are working OK (technews.msaccesstips.com, vbasic.msaccesstips.com) but the main site (www.msaccesstips.com) not working and showing some error related to the themes on the dashboard. The error messages from the theme option are given below:
