This is
NOT a database error, as DeadBattery clearly stated in his post. You should be able to resolve this error by simply uninstalling the mod -- it should have provided uninstallation directions for you, but if it hasn't, then just undo everything you did when installing.
As for restoring files, databases, etc. -- Backups on free hosting accounts are the responsibility of the user. You are responsible for backing up your site in a secure location outside of your x10Hosting account. I would recommend downloading backups of your files and databases at least once a week, and keep them for a month or so.
The administrators of x10Hosting do keep backups of your account, but these are only ever restored when x10Hosting itself is at fault for something (like if your database got deleted during a server move).
EDIT:
To generate backups, do one of the following:
- For filesystem backups, go into the cPanel File Manager, navigate to your Home directory if you aren't already there (it will be the topmost directory you have access to), and then select the "public_html" folder (as well as other folders you want to back up). Once you select everything you wish to back up, click on the "Compress" link at the top of the File Manager, choose the archive type (I'd recommend "GZiped Tar Archive" or "Zip Archive"), and compress the files. Then, download the new .tar.gz or .zip file onto the computer you want to store the backup on.
- For database backups, go into phpMyAdmin, and click on the "Export" tab in the right pane on the home screen. Select all of the databases you wish to back up (do NOT select information_schema!) using ctrl+click to select multiple databases. Keep the "SQL" option selected under the list of databases. Leave the Options as-is, and make sure that "Save as file" is checked at the bottom. Select "gzipped" (this is important! Do not select "zipped" as it cannot be easily restored!) and hit "Go" to back up your database. Then, save the file.
To restore a backup you've made, do one of the following:
- To restore a filesystem backup, upload your .zip or .tar.gz to your home directory in the File Manager. Then, select that archive and choose the "Extract" option
- To restore a database backup, choose the "Import" tab in phpMyAdmin, browse to the file you backed up, and then submit the form
