The blank screen error is to do with options.php. When I checked the debug logs it came up with ...
Code:
syntax error, unexpected T_ELSE in /home/.../public_html/includes/classes/zen_lightbox/options.php on line 53
So I took a look at the code and I'm not sure if its a typo but if you look around line 53 you will see
Code:
if (ZEN_LIGHTBOX_KEYBOARD_NAVIGATION == 'true')
{
echo str_replace(' ', '', ZEN_LIGHTBOX_NEXT_KEYS);
}
echo ']';
else
{
echo 'false';
}
?>
If you look I've highlighted the offending echo in red
You need to move this. I'm not sure where it's meant to go or if its even meant to be there but for a quick fix I just moved it to the bottom of the file. for E.G...
Code:
if (ZEN_LIGHTBOX_KEYBOARD_NAVIGATION == 'true')
{
echo str_replace(' ', '', ZEN_LIGHTBOX_NEXT_KEYS);
}
else
{
echo 'false';
}
echo ']';
Hope this helps
Sorry about the long winded explanation but I find if I explain things like this it helps people debug errors in the future ;)
