Unsuccessful converting

[dziugas_petrus]

Hello,
lately I had a lot of problems with PHPBB. Finaly this forum crashed, so I decided to try SMF forums. Everything is great, execpt, that when I am trying to convert forums from phpbb to smf I'm getting this error:

This query:
UPDATE `joey_herojus`.smf_topics
SET id_first_msg = '',
id_member_started = '0', id_last_msg = '',
id_member_updated = '0', num_replies = '-1'
WHERE id_topic = 640
LIMIT 1;
Caused the error:
Duplicate entry '0-7' for key 'last_message'

When I'm trying to reach forum, usually I'm getting blank page. Please help me

Hi, welcome to SMF. To which version of SMF are you converting to and which phpBB version are you converting from?

Hello, thank you for your answer. I'm trying to convert from phpbb 3 to SMF 2.0.2

Can anyone help?

I'm not 100% sure but I think the cause of this problem is that your host has session.save_path set to a non writeable directory. Please ask your host to change this setting in php.ini and use the correct path.
