It looks like not all the files downloaded properly. The host was acting weird last night. Everytime I tried to download anything it would time out and disconnect. Now it appears when it did work it didnt download all the files properly.
I don't unzip the .zip - but upload the full .zip and unpack it on the host through shell.
If shared hosting doesn't offer this, and the host is acting up .. perhaps consider upgrading to a more serious solution: VPS. Small VPS accounts usually are equal to the costs of shared, but add so much more, including full control of the accounts, software, and their settings. Perfect for a social and dynamic community site.
Be very careful what you're doing.
If you upload the full 1.0.4 package then there's a chance you will lose all attachments and avatars.
At the very least you will need to download those two directories from your old host.
You need to upload the upgrade package.
Also, if you have any add-ons installed then they won't be included so will need to be uploaded separately.
Your posts are stored in the SQL database, which needs to be exported from your old host and imported into your new host/database.
Download the FULL directory, and get the .SQL dump of the database.
Restore it on the new host, update config.php - check if .htaccess is there, and you are good to go after chmod on the internal_data/ and data/ dir.
if moving between hosts is not something you're experienced with, and you still have access to both hosting accounts, perhaps consider the xenforo move services we offer at xenfans.com - our team member mikey has experience with it and if he has the time surely he has no problem helping for a fee. Perhaps worth considering.
Could he not upload the full installation to the new host then upload the backups overwriting the files that the backup still has and using the full installations files to fill in the blanks of sorts where the backup download missed files..?
Also does your old host have cpanel, you could export a backup of the home directory and the sql individually and save the two tar.gz files as backups so you don't have to worry about losing anything as you continue to sort your issues, or even do a
tar -zcvf foroBackup.tar.gz /home/rostaria
on your old server from CLI to manually backup the home directory and then simply download the archive you created
. This is of course only if you still have access to your old server.
