Dear Support Team

I have a big problem. I can not access my site anymore after the update of Joomla and the following error appears:

Error: Error decoding JSON data: Control character error, possibly incorrectly encoded.

Can you please have a look at this. I do not know why this error occures.

I highly appreciate you help as the situation is quite bad for me.

Best regards
Patrick
Hey there,

The reason that caused this issue out is due to your j-konnect-jproject template. Because its Json has invalid data as shown in the screenshot.

I had helped you to comment the following PHP code temporary at Json.php which is at JoomlaFolder/libraries/vendor/joomla/registry/src/Format/Json.php so that your website can work fine for now:



	if ($decoded === null && json_last_error() !== JSON_ERROR_NONE)

		{

			throw new \RuntimeException(sprintf('Error decoding JSON data: %s', json_last_error_msg()));

		}


Can you consult with your J-Konnect template Provider regarding this issue and see how it goes?
