When I try to display some of the oldest revisions on Esperanto Wikipedia, I am getting an error message:
Fatal exception of type "RuntimeException"
This applies to most revisions of "Main Page", listed at https://eo.wikipedia.org/w/index.php?title=Main_Page&action=history – in particular revisions between 4062 to 4097 (but there might be more with the same issue).
Is the issue possibly related to the page texts missing from the database? If that is the case, is there any chance of uploading them if I manage to recover them from early tarballs (dumps)?
