Really stressed out here.
I needed a working clone of a website into a subfolder so that I can test things out on it, but needed it to have the same content and everything.
I previously tried WP-MU and WP-Hive with no success.
This is what I did:
1. Use WP Backup to backup all the database tables into an SQL file
2. Edit SQL file to replace domain with domain/subfolder
3. Use BigDump with config.php file with new database settings
4. Upload and import SQL file into new database
5. Upload entire previous website root folder into the subfolder
During the upload, the connection disconnects and cannot reconnect and ALL of my websites on ALL the databases at 1and1 stop working both through FTP and through domain access with the error message "connection was reset"
The problem is fixed by deleting the new database.
Clearly something in the clone is wrecking everything so this is no issue with the uploading of the files, but I have no idea how I can fix this.
Doing a manual installation and copy pasting values, installing same plugins, importing settings doesn't work because the previous web designer must have edited some of the php files through a text editor.
Didn't think this would be such a hassle!
Another thing to mention is that in wp_options, I have an entry for "_transient_random_seed" followed by a random set of letters and numbers and the word 'yes'
I have no idea whether this has to be unique or at all what it does.
If anybody has any help or advice, then please let me know as this is really frustrating me now.
