EmonCMS Error Line:1 Column: 84305

Hello, I updated my Raspberry Pi 4, but I don´t know if the problem comes from that.
If I open the Main IP from EmonCMS the failure comes in Chrome and other Web browsers:

I normally get every day an export from Emoncms to my externes Synology. The Failure is now also in the Export. I thought I install the Raspberry OS new and install also Emoncms new to save that issue, but I have the same issue in the new OS, because I imported the data.

While I start the Raspberry, a failure with MariaDB comes. I cannot solve that, that my idea was to make a new OS on the SSD.

What I also found:
feedwriter
Inactive loaded inactive dead 11452 feed points pending write

Any idea how I can delete the failure?

Hello again.
I found the problem with this warning. The extension Google sheets was the problem. I deactivated that, Now is good.
