Today I have released a general bug fix release which patches up 25+ bugs found in the original 3.0 product. It is highly recommended that you upgrade immediately to this release to benefit from the fixes. Existing customers should use their original e-junkie email download link to get it.
You will need to replace your existing /themes/classipress/ folder with this new version. Deactivate the theme first before doing this. Then reactivate 3.0.1 because there are some items that need to be updated in your database.
