Soner, if you can find where this font was used my recommendation is to replace it with a suitable alternative. Even if you purchase it (https://www.fonts.com/font/microsoft-corporation/verdana?QueryFontType=Web&src=GoogleWebFonts) unless the font name is identical and you provide webfont embedded fonts in multiple formats (not all devices support ttf) the message will continue to appear and/or a generic font will be displayed on your site.

Maalesef "verdana baltic" kullanılan yeri bulamıyorum. Teşekkürler...
