Some patched files have been released for the phpBB Connector Version 1.0.2 Beta.
phpbbconnector.php has been patched for cases when "Require Admin Approval" is set to No in CB. This will now activate the phpbb user where the old file waited until Admin Approval to activate the user.
LIMIT phpgui.php (rename to phpbbgui.php) has been tweaked for those users importing or exporting large user databases. This limits it to 2000 users at a time.
There is also a known bug of importing or exporing users with special characters. This patch has not been developed yet and will probably come out with Version 1.0.3 which will hopefully be releaseed in the next few weeks. I think that release is down to fixing that issue and updating the README file that is included in the ZIP file.
Hope this helps,
Greg
