    Lightbox fails with cryptic error

    Asked by Masalamedia on February 08, 2013 at 12:28 PM

    When trying to access my form in Lightbox mode, this error is generated


    v8_build_source.js:49: ReferenceError: V8Config is not defined load ( V8Config.CACHEPATH + form_id + '.js' ); ^


    SOMETIMES the same error appears when using the PREVIEW function in the Jotform Form Builder (Embed Form-->Lightbox-->Preview)

    We are sorry about this, it is a data replication error that occurs on the server your form is on occasionally which causes that to happen. It should clear up shortly but if it continues please let us know.

    It seems to be ok now. did you take action to correct the problem? Just today, this is the third or fourth "mystery" it-will-clear-up-later issue I've come across. This kind of inconsistent reliability (and all the time it takes to figure out WTF is going on) makes it very hard to develop solutions for my clients using Jotform tools.
