After login, any left menu item requires login again, and again

I have found something thru the developer view after logging in to the club website which I will research why this is happening even tho I am specifying to allow cookies for this site in the settings I am seeing this although the alert is not appearing.

<b>It appears that cookies are disabled or unavailable by your browser for your club website.</b>
A cookie is a small file kept on your computer to store information between visits to a website.
<b>Your club website needs to be able to store information in a cookie file on your computer during your visit.</b>
If you do not correct this, you will likely have issues with logging into your club website--
your log in status may be "forgotten" and you may have to log in repeatedly.<br>

I'll try an follow up and see why. There was a Microsoft security update pushed to my laptop on 9/24 and this issue started after that.

try removing all cookies for toastmastersclubs.org

It appears this is an included <div> tag that is not active since it also is in the home page content on my mac after login, and there I do not have the same login issue.

Deleting all the toastmastersclubs.org cookies and logging in again did not solve the issue. 
Not sure what cookies it should have but there is a difference between the cookies saved on the Microsoft laptop and on my Mac. Attached images - hopefully someone can tell me what needed cookie is missing and why.

what is the url you are using to access your club?

6607.toastmastersclubs.org/

@6607  There was a hyperlink to the district in your Main Heading. Links don't work in that field. I don't expect that is related to the issue but sometimes strange things happen when code is in the wrong place.

Any chance you are always accessing the site from behind a corporate firewall?

Same question for clubs 4198747 & 7057227.

Just a (perhaps useless) observation as all three clubs in this thread have all corporate email addresses.
