I have just imported the mysql dumps for the ispconfigdb
Thats the reason for the errors. Your mysql database misses the fileds that have been added in ispconfig 3.0.3. A SQL dump can only be imported if the source and target ispconfig systems have the same version. To fix this, you will have to update the system again and force a full database update. This can be done by editing the files:
and changing the version number from 3.0.3 to 126.96.36.199 there and then rerun the update.
