Hi,
I have a problem with conversion from myBB 1.4 to smf 1.1.11. On the Polish support members can not help me.
Making conversion on localhost (program xampp). Detbase have 150MB. When you convert the script is the step "Converting topics" and nothing is still not happening. I removed the limits from php.ini (wrote -1).
What do i do?

converting a bigger database can take a while.. Do you have javascript  in your browser enabled? then the script should stop sometimes (to avoid overloading the database server) and automatically restart after some seconds.
