If this occur after a fresh installation please make sure that the Database was correctly populated, as it may be related to some bug during the installation process.

However, try clearing your all temp files at /tmp. Looks like your snapshot.php file is corrupted/malformed.

Thx for your reply. I tried as suggested but that did not worked for me. I figured out that I've used dots the database name. That caused the error.

I think we can restrict which characters are valid as database name during installation.

nice .. basically it is a bad style to use dot in database/table/field names due to the dot-notation.

SELECT * FROM this.is.my.database.table;
