I have an Asp.net website , and telerik controls on it. On page load I get ConvertFontToSpanfilter error as an alert. On clicking few times 'OK' on alert i am able to proceed normally.
I am not able to figure it out why it's happening . As i know we can disable the filter but is there any specific reason it's happening?
becasue it's random - right now i don't see on my pages
