I get this error: (I have no users defined)

just after 2x resetting the cache (dev tools / force refresh etc.. ) finally its off .. very wierd cause I had done that already several times .. 

suggestion, could not find it

When books are disabled, will the theme disable the display of the books part? I only have comics.. So I do not want to see that book menu option. When I press it I see .. 

Books sharing is not activate

mmmm nice .. but have to check how that is enabled .. restart server / refresh cache .. .. let me see .. 

update.. Ahhh i see .. it is text .. duhhh .. ;)

I have seen this number block on the black/default theme and it gave me 'always' a number to see how many comics there were in a particular folder. When I change to this theme I do not see any number anymore. :-( .. I do not see a direct reference that a number is going to be displayed. I only see in the CSS 

.numberblock,.number{
display: none;

Where in the black/default theme

there is number.block and

.number span {

1. background: transparent url(sliding-left.png) no-repeat;
2. display: block;
3. height: 39px;
4. padding: 10px 0 5px 8px;

}

Would be great if that could be implemented as well
