Uncaught ReferenceError: FooBox is not defined

Hi @gonzaguegb

This is not caused by FooBox, but rather from a conflict with another plugin or theme that is forcing your javascript files to load using the defer attribute.

It is usually a performance or caching plugin that does this on every script included in the page. I have also seen themes that include some custom php in the functions.php that does this.

Because FooBox loads some inline Javascript (based off the settings) the order of the scripts are loaded incorrectly, and the FooBox init code ends up being run before the FooBox script is loaded in the page, which causes the error you are getting.

I am sorry for this issue, but there is nothing we can do on our side to correct, unless we rewrite the way FooBox is initialized. This is something we are looking at doing in the next major release.

Send me your URL, so I can tell you if your site has this same conflict issue

Please can you try this updated version which tries to cater for when other themes or plugins change the foobox scripts to load in a deferred manner.

Please let me know if that version works for you
