If the file name has # it probably would mean the bookmarks are broken from your project.
Can you try "Check out All", and then try restoring the broken links from -- Tools -- Resolve Broken Links.
Do you have a local copy of the project with you that you can check with?
Can you try replairing broken links from this article?
Thank you for your prompt reply.
What exactly do you mean by restore the broken links? When I open Tools and Resolve Broken links then click Restore, I get the following message:
'You cannot restore a topic that would be outside the project folder. Please make sure the references are to the project folder then try restoring the topics.'
I cannot locate the topics in Robohelp in order to link to them. As far as I can see, the only way to fix the broken links would be to manually create new topics and repopulate them with content. I would have to do this for hundreds of topics. Is there any alternative?
Also, what might have caused this problem, and what can I do to make sure this doesn't happen again?
All the files are intact on the server, and on my C drive. But I cannot locate the missing topics in Robohelp.
I would really appreciate any further help you or anyone else has to offer.
Before this happened, Robohelp had been occasionally trying to check files into source control almost at random, with "lock, edit" as the reason. These were files that had not been worked on at all. No changes had been made to them. Whenever I agreed to check the files in, they would be undone by the server. I don't know if this is related to what went wrong after that, but I suspect it is.
