Hi everyone.
I have a problem with converting the forum from mybb to smf on startup crashes something like this in the attachment.
are you putting your SMF files in the same folder as your mybb? if so you cannot do it like that, you need a separate folder/directory for the SMF files separate from mybb.
Yes keep it separate. You need to keep your MyBB install, and have one install for SMF. After conversion you can then remove the MyBB. The SMF converters do not touch the MyBB database structure.
