t\wp-includes\pluggable.php on line 2292 | WordPress.org

Hello,

This is a known issue which will be fixed in the next plugin version (1.7.8). These PHP warnings (not errors) do not affect plugin’s functionality (so you don’t really need to deactivate the plugin).

This said, the fix for this issue is already implemented in plugin’s development version:

If you don’t want to wait for the next version release, you can use the development version and update to version 1.7.8 when it becomes available (as you normally do).

Let me know if you need more help.

Thank you, the file you provided is working properly.
