 * Hey,
    Sorry to hear this! Can you confirm that you’re running the latest version
   of Pinnacle? And that your plugins and WordPress core are all up to date? If 
   so and the errors remain, I suggest deactivating your plugins to test if any 
   are conflicting. Let me know if there’s no change!
 * Kindly,
    Hannah
