 * Hi,
    During loading I checked page loading sources as the Postgrid category tag
   collection, is taking too much time to load.
 * The error is:
 * Error parsing header X-XSS-Protection: 1; mode=block, 1; mode=block: expected
   semicolon at character position 14. The default protections will be applied.
 * Regards,
 * Henny

 * Hi,
 * The error is appears as soon I activate the Security headers in .htaccess
    I 
   found in the meanwhile the solution:
 * I am using Really Simple SSL Pro. When I directly activate the security header
   Network wide the error is there.
    Activating the header, site by site, resolved
   the issue. Now there is no error anymore when loading the page.
 * Thanks for your support!
