On some WordPress installations, using PowerMag template which includes JackBox plugin for lightbox effect, there is a problem loading the graphics of the Jackbox plugin which results in getting 404 not found errors, because of a relative path.
The theme author haven’t provided a solution to this yet, so I’ve found the fix below:
To fix this, you have to edit the jackbox-for-powermag.min.js file, search for:
"?jackbox_path=../img/graphics/"
and change to:
"?jackbox_path=/wp-content/themes/powermag/inc/jackbox/img/graphics/"
you can not imagine what a big help you have done for me … thank you very much
