I've got this problem after migrating SMF (1.1) to myBB, using the latest merging system.

The merging progress seemed to be ok, no errors reported. I can see attachments on posts and on the admin panel as well. However, the problem is: most of attached files are corrupted or damaged which can not be opened with the message "The archive is either in unknown format or damaged". Some attached can be downloaded and opened, but their contents are different from what they were expected (they all have the same content even with different names).

Is there any ones experiencing this trouble? Or, is there any solution for this?

Also, I still keep all attachments assigned to the old forum (ie: SMF one). Do those stuff bring any help? Can I use them for doing something to solve the problem?

Thank you so much for your helps,

Huy
