Hello

 

We recently update from really old IPB version to IPS 4.4 and we face the following issue : the old post  were in BB code and it seems that they are no more interpreted. 

 

So they look really awfull.  Any clue around this problem ?

When you upgrade, several background tasks are kicked off that rebuild post content in the background post-upgrade. You can monitor the progress of these tasks in the AdminCP on the dashboard by expanding the "Background Tasks" block. If you still see several tasks there, I wouldn't worry about the old post formatting. If those tasks are gone and you're still seeing bbcode, submit a ticket.
