Oh, right - 'Rebuild Custom Avatar Thumbnails' would only affect custom avatars, and we're looking for default avatars.

If your Recent Posts are cached it could take some time before it rebuilds. I think there's also a 'clear system cache' option somewhere that may do it. ETA It's a the top of the "Maintenance" menu in the adminCP.

Thank you for all this help. Can this script be modified to fix my signature and profile broken links as well?

Are they avatar related? I don't know how to answer because I don't know why they're broken. Signatures may be in the post cache, so you could truncate the postparsed table (or use rebuild post cache in the maintenance menu) and see if that helps. I don't know what the profile problem is.

All related to the same issue. I was hacked last month and my entire images folder was lost. So anything that was stored there, avatars,profile pictures and attachments were lost and now show as broken. My skill level with this type of thing is low. I apologize in advance.

Oh, I see...well, I think it probably can be modified to fix the profile pictures. I'm not sure about attachments. I suppose we could use the same method to remove broken attachments from the database, but I'm not sure what that will do to posts that include one - they still may end up as broken images.

Ok no big deal. You have really helped me out. The site looks a lot better without all those broken thumbnails. Thank you again.

OK, but profile pics turned out to be almost the same as avatars, so I'm attaching a modified script for that. I could look at attachments if I get a chance, but I think it's going to be more involved.

Great. Thank you for yet another script. I will upload and run it right now.

@kh99 , Please can you let me know, does fixavatars.php and fixprofilepics.php are still working for vB 4.2.3 ?

Sorry, I don't know, and I don't really have time to set up a test. But I can't think of any reason why it wouldn't work. I don't think there's been any major database changes since then. It would be ideal if you could could close your forum and make a database backup first, then try it, so you can just restore if it doesn't work. Or better yet, try it on a test forum first.
