Sorry for the downtime. The SQL database was flooded with errors and 1and1 refused to migrate it to a new database for me. Let's hear it for grade-A customer service! Thanks, 1and1!
At any rate, I finally finished migrating over from the old 100MB database to a new 1GB database, so we should be fine even if there's another error overflow of some kind. The migration, by the way, is a huge pain in the ass because I have to segment the SQL table file that holds all of the forum posts. Even though 1and1's "limit" for SQL file uploads is 49MB, it fails on any upload larger than about 4MB... yeah. So I had to segment out the entire table of EVERY message on the forum into eight or nine files MANUALLY. Thanks, 1and1!
Please report any abnormalities you see to me-- though I'm pretty sure things are 100% back to normal now.
