Getting PHP warning error

If you have a DSO Host server type:

These errors are occurring because the BPS DB Backup folder does not exist or is not writable. The BPS Backup folder should be created automatically here: /wp-content/bps-backup/backups_xxxxxxxxxxxxxxx by BPS during the upgrade or on new installations of BPS, but if the /bps-backup/ folder does not have the correct Ownership settings to allow for this folder to be automatically created then you will not see this folder. You can create the DB Backup folder manually and then save the folder path and URL path information on the DB Backup page or you can allow the backups folder to be created automatically by figuring out what DSO Ownership settings you need.

If you have a CGI Host server type and there is a permissions problem for the /bps-backup/ folder then you would change the /bps-backup/ folder permissions to 755 or 705.

If something generally just went wrong with the automated DB Backup folder creation then you can either manually create the /wp-content/bps-backup/backups_xxxxxxxxxxxxxxx folder and manually add your db backup path settings on the BPS DB Backup page…

…or to allow BPS to automatically create the DB Backups folder again and add the db backup path options settings again – Use phpMyAdmin or another DB editor and delete this BPS database option: bulletproof_security_options_db_backup and delete this folder if it exists: /wp-content/bps-backup/backups_xxxxxxxxxxxxxxx folder.
