Love this accessory by Brandon Kelly / P&T:
Works like a charm. Only now, I'm getting this error in the developer log:
Deprecated function generate_json() called in system/expressionengine/third_party/module_nav/acc.module_nav.php on line 82. Deprecated since 2.6. Use the native JSON extension (json_encode()) instead.
Appears to still be working but the forum at devot-ee is closed. Anybody know if this is still supported by the developer? Or what to do to upgrade it? Tried swapping out the function but it failed.
