I just movde my site from a dev subdomain, to the root. I have extensive amounts of data saved in custom meta fields which I created with the WpAlchemy class. All of this data is not appearing in the site (back or front end), although it appears to be in the database.

This happened right after attempting to use the search replace plugin to change any lingering urls. This attempt ended in Fatal error: Out of memory. I noticed everything was gone, so I swapped out the db for my backup (after doing a manual search-replace for my subdomain). This produced the same result.

I think I've read somewhere that data serialization (am I getting this right?) can mess up this kind of thing. Is that whats happening to me here?

What steps should I take to get the site up and running ASAP. Currently it is live, and terribly broken :-(
