Some time ago I suggested some improvements for Importer when dealing with import from IPB 3.4.x ( Importer: some bugs and ideas to improve data import from IPB 3.4.x ).
Most of them are now fixed - thanks (I replaced file IPB3xExporter.class.php and run conversion again today), but I spotted two issues. I will create separate threads for them as second one is more complicated.
First issue: quotes are missing author name. In original post in IPB it looks like this
In database this is saved as:
After conversion I got in WBB:
Generally I see in database two kind of quote types - with blockquote tag shown above and simple BBCode [quote name="some name"].
It is possible that there was some change in the way of dealing with quotes at some time in IPB and thus two kinds are present in my database.
