Upgrade problem, board will new install


Active member
I have uploaded all files, everey time the board will new install :(

First upload my FTP Client (Transmit) delete files on server before uploading.

My second upload I used Filezilla but url/install will now install new xf and will overwrite database.

Uploading old xf 1.0.1 not success because install not complete (lock file is deleted)

what can I do?

You can create a internal_data/install-lock.php (empty) and that's all that's needed. (You may need to recreate your config.php too).

I should note that you may have lost avatars and attachments, if your data and internal_data directories are missing. You'd have to restore those from a backup.

I have do

You have already completed installation. If you wish to reinstall, please delete the file internal_data/install-lock.php.
The file is empty

Attachment folder ist not empty

It sounds as if you may need to upload the files again.
It's possible there were some problems during the FTP process.

I just had something similar, I was upgrading from 1.0.0 to the latest version and upload the files with Transmit but it looks like they deleted something as it forced me to do a clean install.
