I were trying to upgrade my website to version 3.0, After i tried upgrade this happens:
Only a blank page appears with message:
"Error: A theme has not been assigned to this store!", i read about permissions and tried everything a nothing works.

I get back with my backed up files to version 1.5.6.1 and now i got this error messages:

Notice: unserialize(): Error at offset 0 of 5 bytes in /home/emorelos/public_html/index.php on line 69

Serialize and unserialize functions have been deprecated by the PHP industry. It would be recommended to upgrade to a higher version of Opencart if this issue still persists.

Dedication and passion goes to those who are able to push and merge a project.
