Unknown column 'a.attachment_type' in 'field list'
I got that after upgrading from 1.1.16 to 2.0.1
Site: Venom-rs.net
Did you run upgrade.php after uploading the new files?
If so, try running this query in phpMyAdmin:
ALTER TABLE smf_attachments
ALTER COLUMN attachmentType attachment_type tinyint(3) unsigned NOT NULL DEFAULT 0;
i would say they have not run the upgrade.php script as it is still on their server

Thank you! I didn't see a documentation which is why I didn't go to upgrade.php
