Fortunately I made a test forum a couple of days before switching the real forum, and in that one I did save the import logs. So I just imported the table to my current forum database and since id's were the same it worked.
I'm a bit confused. I just imported vB 4.2 with vBSEO into XF and saved the import log.
I have vBSEO Likes Importer installed and then the instructions say "4. Go to Tools > Import External Data > vBSEO Likes and run the importer! "
But there is no mention of "vBSEO Likes" on the page after clicking 'Import External Data'.
I tried re-installing the add-on. What am I missing?
