I'm sending an ICS file in email attachment to users, these events were added to the user's google calendar automatically, but now this functionality has stops. The ics file is:

BEGIN:VCALENDAR

CALSCALE:GREGORIAN
METHOD:REQUEST
BEGIN:VEVENT

This ics is working when we manually import ics file in google calendar, but events does't added to calendar automatically once the user get email in recent time earlier it was working. I have already checked the google settings for "automatic add event from google calendar", what change I need to do so that the event from ICS.

Image is stored in the rich text area, I need to display the image in salesforce site which is created using VF page, the image is visible earlier but now I don't sure but there are some changes for salesforce site guest user policy in the recent release, I want to know what changes I need to make to display the image.
I am displaying the image on page load, earlier the image is visible as shown below screenshot:

But now in place of the image, a text is appeared "Image is not available because you don't have the privilege to see it or the image is removed from the source" as shown below screenshot:




I am using this code on vf page.

<img  src="{!extractedUrlFromBacked}"   height="55px"/>
