This the code I changed to temporarily 'fix' my sidebar issue (chose 'left' instead of 'right'):
### POSITION OF YOUR DEFAULT SIDEBAR ### # Right, left or none? set comp_state = "left";
- "Thank your for your report, and I apologize for the delay in responding to your request. Because of the complexity of your question, it took longer than normal to provide an answer. It appears that your custom theme layer contains code that is no longer compatible with recent changes to the Component layout layer.
Unfortunately, it is simply not possible for LiveJournal developers to test every possible combination of users' customizations for conflicts when making changes. You will need to either edit your current custom theme layer so that its code is compatible with the current Component layout or change to one of the system-provided Component themes, which you can then customize to your liking. You can change to one of the system-provided themes from the "Choose Journal Style" page here [http://www.livejournal.com/customize/].
If you prefer to edit your current theme layer, you can do so from the "Your Styles" page here [http://www.livejournal.com/customize/advanced/styles.bml].
The FAQ linked above provides more information on how to use the Advanced Customization area."
