it came to my attention that some posts were empty after being imported. I cannot tell you what exactly caused this and maybe it's a connection of unhappy circumstances, but well...
How it all started, as far as I know.
There was a WoltLab Burning Board 2 in which we posted some source code we created at school with Turbo Pascal (yes, for DOS).
Then, there was an import to vBulletin 3.6 with upgrades to 3.7 and 3.8. And now there was the import to XF.
There are posts that contain umlauts from ASCII (in the source code) and it looks like that is the issue.
Some other posts were imported empty when there was the output of GZip in (like when headers are sent and you send GZip output).
This thread is just for reference, I will PC Mike for further information as he already has my database (unless he deleted it).
