Hi I wanted to convert vBulletin 4.2.5 to SMF 2.0.17 I get the error shown in the picture.

What PHP version are you on? And what convert.php file did you use/where from?

PHP Version 5.6.30

Hi the converter.php from https://www.simplemachines.org/community/index.php?topic=404729.0 downloaded from the first post

Grab the convert.php from and replace and see if that helps

Thank you very much for working with smf_2-0-vbulletin37_converter converter.php

Which converter should I get? In the download area I find 5

for vBulletin 4 try https://www.simplemachines.org/community/index.php?topic=404729.0 I would grab the latest convert.php though from any of the convertors.
