monkh6632 If you have two separate sites using the same database, you'd need to make sure they're using different tables otherwise they'd end up overwriting each other. In the setup phase you can specify a table prefix - just ensure you're using a different one for each.
Now if they're both overwriting each other it may be easier to start from scratch, so by far the easiest option is to start again on one of the sites, but use a separate table prefix.
If you've already got both using the same DB and need to change one, it's specified in include/ost-config.php - look for the following line:
# Table prefix
define('TABLE_PREFIX','ost_');
Note that doing it manually means you'd have to create the tables yourself (copy and rename the existing ones), so if possible, starting again while specifying a new prefix in the setup phase will be a lot less hassle.
