Dues error message

Morning,  I have been getting this error message for the last 24 hours.  Should I do something to my browsers windows I have tried it in Mozilla Firefox and BRAVE browsers. Same error message.  This is for my club #1196053 Confident Communicators Club. 

Any help will be appreciated, Anita  

Please click the Reload link at the bottom of your site and try it again.

I have "OK" to reload it 3 times so far. it just keeps taking me back to my Club's home page.

Weird question: should I try clearing out the cookies? then load the webpage?

You have an incorrect variable name entered.   {{club name}} should be {{clubname}}... no spaces.

I will have to fix it when I have some spare time over the weekend.
