I guess that a JavaScript inline comment is causing this error. W3 Total Cache (and other tools to minify the source code) removes all line breaks which results in one big “disabled” JavaScript call.
You might try to directly edit the source code of the FooBox plugin to solve this issue, however each update of the plugin will reverse this fix!
Open “foobox-image-lightbox/includes/class-script-generator.php” and goto line 172. Replace
$preload = ' //preload the foobox font
with
$preload = ' /*preload the foobox font*/
Hope that helps.

Thanks for your answer! Would be so sweet if the authors would fix it with an update – but they do not response at all :-/
PS: Unfortunately your solution does not work. Even after replacing this code the lightbox does not show up when clicking on a picture. The picture itself just opens in a new tab. Without cache it works, but with W3 total cache: No.
What else may I do?
I now also changed every “//” to “/*” and at the end “*/”. But it does not work either… I don´t know why this plugin does not work when cached.
Would you mind sharing the link to your website? 🙂
