Thanks for reply
I use the latest versiom: AtahualpaVersion: 3.7.24
I normaly use Lightbox JS v2.2,
I have tried with disabelling all other plugins with no result.
Works with Twenty Seventeen Version: 1.1 and MH Magazine Themes.
I use pro version of Envira gallery with addon: CSSaddon, Gallery Themes Addon, Defaults Addon, Gallery Themes Addon, Slideshow Addon.
Doesnt show any errors :-) exept doesnt activate lightbox - with or without lightbox 2 activated or not.
Envira Gallery support says: "theme conflict - since it works with most other themes"
Atahualpa doesnt load the Lightbox with or without addons activated (does so in other themes).
(Aditional: I Had to insert the most important css into ata css options to make choise of envira gallery theme work)
Tryed instalation of both atahualpa 3.7.24 and Envira on more websites with same problem.
If you like I will provide you with admin login (please tell me how tha could be done outside the forum)
