js issues – cause problems else where?

hi, I’m currently experiencing issues with another part of my site and it has been suggested that the event manager plugin might be the issue as it has js script issues.

i get:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (quick-event-manager-custom.css, line 0)

[Warning] Unexpected CSS token: : (services, line 90)

[Log] hey (quick-event-manager.js, line 151)

come up in my error console for this page http://www.sptestplatform.com/services/

can anyone let me know how to fix these issues please.

Thanks
