Exception error after running for a while

Hi Corie,
I’m trying to migrate my website from GoDaddy to Krystal hosting in the UK. I’ve created an archive on the live server and copied to 2 files to the new server using FTP. DNS is pointing to the live server at GoDaddy. I renamed the installer.php file to remove the GUID stuff at the front of the filename, but left the .zip filename alone. I then changed the hosts file on my PC so it pointed at the new server and ran the installer.php file. This ran for about 40seconds, created a load of folders and >5000 files, but then fell over with an Exception error with the following message:

Message: FILE ERROR: put_content for file /home/c1racing/public_html/dup-installer/classes/../dup-installer-state_bae012d-13155654.txt failed [dir /home/c1racing/public_html/dup-installer exists but isn’t writable]

The trace looks like this:

#0 /home/c1racing/public_html/dup-installer/classes/class.installer.state.php(86): DupLiteSnapLibIOU::filePutContents(‘/home/c1racing/…’, ‘{“mode”:0,”ovr_…’)
#1 /home/c1racing/public_html/dup-installer/classes/class.installer.state.php(76): DUPX_InstallerState->save()
#2 /home/c1racing/public_html/dup-installer/main.installer.php(181): DUPX_InstallerState::getInstance(false)
#3 {main}

Do you have any ideas?
