visitors cannot see data

The only widget that is not displayed to visitors is the “My predictions”. The rank and the table should be displayed normally. What is the link of your website?

https://www.zenred.com

the results page works for visitors

the widget works when the visitor is on the results page

but the widget does not work when you are on a different page (read Main blog page)

What widget does not work? Here is appearing normally.

both

WCP standings

and

WCP Top Ranking

it is real weird if you are not logged in
these widgets work when you are on the pages that show the results or the page to enter your own Predictions

but it you go to a different page the widgets show 0 for values

Could it have something to do with the template I use?

I use Magazine Basic By c.bavota

There should be no conflict with your theme, but it may be something related to it yes, or some other plugin you are using. The ideal would be to check if the extract($args); is working or not.
