Export Error

Hello, I recently received an error message when I tried to export my font. I did some research here and there was a similar bug posted earlier this year. The thread starts with this: (I am reporting the same problem). After following the thread, I am still unsure how to fix it. I would love help, thank you!

"I appear to have made a change to my font that is causing an error, but I can’t find it. It manifested when I tried to export the font. As OTF, the font simply appears empty with no glyphs. As TTF, I get the following from running generateFont.command:

makeotfGlyphs [FATAL] — Source font: font.pfa
makeotfGlyphs [FATAL] bad CharString format
logout"

The glyph names were not okay. Read this, please:

Can you try to disable the autohinting?
And what version of Glyphs do you have?
