Why can't I edit my user bio, interests, or old entries?
If you have used unusual characters in your interests, any of your entries, or your user bio, you will be unable to edit them until you set your default text encoding and mass-convert your information. If you see question marks (?) anywhere in the entry or bio you are trying to edit, visit http://www.livejournal.com/support/faqbrowse.bml?faqid=133 for information on how to do this.
Occasionally, use of improper HTML can render your entries uneditable. If you are unable to edit your entries using the Edit Entries page (http://www.livejournal.com/editjournal.bml), you can try editing the entry directly, by going to the comments page for that entry and clicking the blue pencil in the toolbar above the entry. You will need to be logged in to see this icon. More information on editing entries can be found at http://www.livejournal.com/support/faqbrowse.bml?faqid=2 .
If you are still unable to edit your entries using the web client, you may wish to try downloading a client for your platform and using that. Clients are often unaffected by improper HTML, and you may be able to edit the entry in that fashion. For information on clients available for download, please see http://www.livejournal.com/download/ .
