Hey @tobonda .
Thanks for reaching out.
I appreciate that you have included a screenshot of the error message you are seeing. To gather some additional context, are you receiving this error message when you are attempting to load into your online store? If so, I would suggest attempting to clear the cache on your browser and try to load back into the store.
If the error persists, I would then suggest attempting to use a separate browser. As for example, if you are using Safari try this action on Google Chrome.
Let me know if that does the trick, looking forward to your response.
