A couple months ago the sight started rendering text only with MacOS and Safari. Works fine on Chrome and iOS for whatever reason.
My iPhone has issues posting if the txt string exceeds the first line with Safari, but works fine on the iPad
clear cache and try again.
How to Remove Cache on Safari
Open the Safari Browser.
From the Menu go to Preferences.
Go to Privacy then click on Manage Website Data.
Type the name of the website in the search box.
Select the website and click on Remove.
Chances are there is something sticking in the website cache that shoudn't be.
Worked great
