No name specified after event marker in template &1.
&1 - The template containing an event marker without a name.
While handling a template, an event marker "/(FORMEVENT- )" has been found where no name follows the -.
This means that the runtime cannot determine which event to generate the HTML for.
The generation of the page has continued without errors - but without generating anything for the event marker marker - which will lead to errors when the user activates the event.
Insert the name for the event in the eventmarker.
