Answers.Text: Thank you for the hint Guitarman.
  
  I have disabled all the Filters in "Request Filtering" and in a second step disabled the admin tools WAF by unpublishing the System - Admin Tools plugin. That leaves the enhanced .htaccess file.
  
  However, there is no change at the Event-Page, still the code at the top. As I had experienced odd (cache) behaviour in Firefox, I checked with a chromium browser, but same behaviour.

  Most probably, **AdminTools by Akeeba** is blocking a request.
  
  Please try to deactivate
  
  PHP stream wrappers block (PHPShield)  
  Direct File Inclusion shield (DFIShield)  
  PHP session data poisoning protection (SessionShield)
  
  from the WAF/Request Filtering section or temporarily deactivate AdminTools.
