When I try to use my WA I get the error message that this is for Classic instead of Retail.

I typed /wa and expected to get the menu since none of my WA have launched since my last update. Which is highly problematic since I use my WA to see a lot of information.

Use this version: https://github.com/WeakAuras/WeakAuras2/releases/download/2.14.6/WeakAuras-2.14.6.zip
