  • This is the entire error being posted at the bottom of pages in the backend.

    Fatal error: Cannot redeclare class services_json in /info/wp-includes/class-json.php on line 115

    Problems with your backend, eh? 🙂

    If you’re feeling adventurous, you could try installing 2.9.1 rc1, there was a bug fixed in that which might solve your problem.

    You should be able to grab it pretty quickly by following the instructions here (the current release is 2.9, despite what that says).

    Thanks for the fix..two changes to class-json.php and all is well

    They fixed this bug in v1.0.1:

    Fixed Bug #16585 – Fix correct mime type for encode() – note use encodeUnsafe() to prevent headers being sent.

    So yes, updating our wrapper to use encodeUnsafe() should do the trick.


    Please mark resolved.
