Moving SQLite-D7 Installation to other Server throws Uncaught exception in shutdown function
It seems that the PDO SQLite driver requires that if you are going to do a write operation (INSERT,UPDATE,DELETE,DROP, etc), then the folder the database resides in must have write permissions, as well as the actual database file.

The above information is taken from another answer: https://stackoverflow.com/a/3330616/2171489

I don't use SQLite, but given the error from the PDO driver and the fact that you moved to a different server, it does seem like it could be a file permission problem.
