Hi,

I get what looks like the same error on my local version of WordPress after updating Piklist and WPHelpers.
i.e.
Warning: extract() expects parameter 1 to be array, null given in C:\xampp\htdocs\wordpress\wp-content\plugins\wp-helpers\wp-helpers.php on line 387
This has happened a number of times in the past after updates to either Piklist or Helpers. Normally I have to clear out both and re-install them.

After this latest update it has happened again but it only breaks the system after I activate WPHelpers. Piklist on it’s own is ok but once WPHelpers is activated it prevents any updates via the Dashboard.

Interestingly this problem is only occurring on the local Windows version. The Unix hosted version of the site is unaffected.

Hope you can help.

Regards

Phil
