Muse keeps crashing everytime I try to change font in one certain page of a site that I am planning. Error message: No_overlayHeaders? What to fix the problem?!
What kind of font do you want to change to which font? System Font (bad idea) web font, self hosted font?
Screenshot, where you want to change the font might be helpful.
For getting in depth and identifying the root cause of the issue, can you please try copying the whole text box into a new page and then try changing the font.
I fit still crashes please share the same file here via Dropbox so we can also have a look at it.
The problem solved when I changed all Proxima Nova Alt fonts in the page by deleting paragraph styles including this font and replacing them. Trying to change font directly always ended up shutting muse with the above mentioned error..
