Hello,
These are just notices, not errors and they are displayed because your server is set to display all PHP messages. You can fix them if you edit file hot_gallery.php and around line 91 change this:
if(!$options['ImageFolder'])continue;
with this:
if(isset($options['ImageFolder'])) {
if(!$options['ImageFolder'])continue;
}
and in file around line 88 change this:
if(!$options['ImageFolder'])continue;
with this:
if(isset($options['ImageFolder'])) {
if(!$options['ImageFolder'])continue;
}
Also, we will upload updated theme files soon, so you can reinstall the theme if that’s easier for you.
Thanks,
Milos
