Snapshot + Multi-DB Error


When I try to do a backup I get this error:

Unknown: errno:8 Use of undefined constant DATACENTER – assumed ‘DATACENTER’ ***/public_html/wp-content/db.php on line 287

    @tomasz, The file from the referenced error is not part of the Snapshot plugin files. So my assumption is this is related to your Multi-DB setup.

    Can you open the file and let me know what line 287 reads?

    Normally this PHP error is related to a PHP array element that does not have proper quotes for the item key. Meaning the array element is written like

    some_array[DATACENTER] instead of some_array[DATACENTER]

    Then again since DATACENTER is all uppercase this usually implies a defined constant. Might be helpful to have the entire file. Can you send to paul [at]
