 * Hi Michal,
 * Thank you for reaching out to us.
 * Can you provide more details as to how we can replicate this? Did this happen
   when you tried to update the Kadence Blocks plugin?
 * I looked at the error message and it looks like an upgrader issue. When I updated
   Kadence Blocks to the latest version I didn’t receive this fatal error though:
   [https://nimb.ws/g3Ju0sN](https://nimb.ws/g3Ju0sN)
 * Can you try manually installing the latest version instead? Then check again 
   if this happens on the next update of the plugin.
 * Let us know how we could help you further.
 * Kind Regards,
   Michael Taro

 * Hey just to add, we changed a part of the code in the latest update, while we
   couldn’t recreate this just using the log shows that null was passed instead 
   of a string in a filter args so we updated to allow for that.
