We have several webchecks which use macro's to retrieve the URL, String and optional credentials.

The template that contains the webchecks and triggers also has a screen with the graphs with Download Speed per item.

The parameters are not being replaced (in the title of the graph) so it shows "{$URL1}" and the graph contains no data.

Also, the bottom of the page shows the following errors:
