I can only repeat:
You should start from scratch. Load the DW files on your new server and run install.php. Go through all the steps required there. Then you will be a superuser with permission to read, write, delete, and upload. Do not overwrite the new configuration files. If you have config data from a previous installation, then recreate that data non-destructively on this new install. If you had other users and other permission settings, you can append their config data to the new config files, but make backups before you do this and don't delete anything from the new config files.
If you insist on using softalicious, then you can still follow the steps after the install as described above.
If before you edit the config files you cannot read,write,edit, and upload as superuser, then there is something weird going on on the server. If it works, then try testing: you can try adding to the newly created config files gradually (you've backed them up) and see where things break down.
