phpBB 3.0.7 to SMF 1.1.12 converting members ERROR

[adjie]

hi folks

I hope this is not too much to ask
I have searched the forum but did not find similar problem with mine
My apologies if it turns out that there are...

I tried to convert phpBB 3.0.7 to SMF 1.1.12
I followed the manual instruction as follow:

• I put SMF files in sub directory A
• as for phpBB files they're in sub directory B
• both of them are using the same MySQL database (the one I created when I installed phpBB)
• I used Phpbb 3 to SMF 1.1.12 converter
• I put all the required data correctly

However when I ran the conversion, I received this message error:

Converting members... Unsuccessful!
This query:
SELECT ID_ATTACH, filename
FROM `dhbase_phpb1`.phpbb_attachments;
Caused the error:
Unknown column 'ID_ATTACH' in 'field list'

I am wondering what might cause the problem and how should I fix it?

Thank you in advance for your kind assistance

Regards,

Adjie
