Version 5.46a

My plan was to archive a thread. So I went into the control panel, created a new archive and verified everything was created.

Went to the thread to archive, selected the archive I just created, clicked submit and got this error:

"This topic has already been archived there. We cannot archive a topic more than once to the same archive. Please go back!"

Unfortunely the topic is not really archived there in /Archives. I looked and the sub directory Archive-000001 is empty. Yes Archive.pl is there and it lists the first arcive:

000001|#|Vibrations 2000|#|Vibrations due to tires, May 2000

Everything is chmoded 777 correctly. Any suggestions?
