    Lightbox effect stopped working on my Gallery posts. It was working fine previously, but now just opens the image in a single window. Here’s an example:

    Lightbox works fine for Video posts:

    Thanks in advance for your help.


    Fixed it. Turns out I had “Prevent caching of objects after settings change” enabled in W3 Total Cache in the Browser Cache>General settings. Disabling it fixed lightbox for some reason.

    I would like to understand how that affects prettyPhoto for future reference – if you can take a moment to explain why that would be great.

    Thank you.


    Hi hughjaas,

    I have no idea but your best source for an answer would be with W3TC or to ask on the support forums for the plugin.





    I thought your site is about people interested in having affairs. Must say after reading a few articles, I was disappointed. :)

    Devin is right, don’t bother with the technical stuff, unless you really want to know than you need to start from the foundation.

    Not sure if you want an answer to your questions unless you are technical, in that case your best bet is to read (google for) “Optimizing the resource-updating period behavior of HTTP cache servers for better scalability” by IEEE or Google’s “Dynamically allocated secondary browser cache” the second chapter of section thirty or the thirtieth chapter of the second section. Can’t remember but good reading…. ughhhh, at least there won’t be an exam for you.
