I have a big problem with my Joomla Templates: A few months ago I have created an Joomla Template which I opend a few days again in template toaster and changed only the font-family of the headlines. Now if I open the Webpage on a PC the headlines are like they should be but if I open the page on a mobile devices the font-family changes to Arial or Times New Roman.
Who can I changes this? In the earlier version of the project all worked well.
Thanks for your help!!
