When I publish my tree, I frequently get the message "Some photos could not be published:. Why does this happen? How do I know which ones have not been published? How can this be prevented?
Can you please tell me which type of photos are you trying to upload and what is the size of those photos?
Furthermore, I would like you to send me the logs report of the Family Tree Builder (FTB) program.
To activate logs, go to Help > About Family Tree Builder, now right click on the window that opens (doesn't matter where) and you will get a few options.
Choose Start Logs and close that window. Try to publish the tree and when it's done, close any message that opens.
Now go back to Help > About Family Tree Builder. And click on Send Logs and send me the file called Send_logs_to_support.zip.
