Hi - when should I repair or optimize a database? I have the DB MAnager plugin installed, and my site's posts (called lessons) are suddenly not showing their contents. I can the contents in the .sql file. I have updated wordpress to 3.5.1 and buddypress to 1.7.1. I have posted my problem in the buddypress forum as well, but in general, does this sound like a database repair issue? PLease advise. I figure I should repair all of the tables. But what is the difference between repair and optimize? Thanks!
