SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

[georgemichaelis]

Hello,
when hitting the "Archive reports" button in the Troubleshooting section of the WP Plugin it says:
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
The Matomo Dashboard is not generating reports.
I attached the system report.
Can you help`?

Thanks.

Best Regards

Hi @georgemichaelis, this is a known issue for some hosting providers. The archiving ran, your browser is just not able to display the page again due to a currently unknown reason.
