Hello,
If you're experiencing an issue / upgrading where you're stuck on the 'New settings' screen in a loop in versions 405.2.4 - 405.2.6, 500.2.4 - 500.2.6 and 501.0.5 - 501.1.1 then please edit (in a suitable UTF8 editor such as Notepad++), 'classes/settings_toolbox.php', line 1496, in the method 'units' change from:
$end = ($end - $start) / $increment;
to:
$end = $start + (($end - $start) / $increment);
I'll make a releases with the fix as soon as I can.
Kind regards,
Gareth
