I'm running plesk 11.5.30 and I'm having an issue with the new word doc format (.docx) being recognized as a zip file. I've read several posts that explain what mime types to add, and I've found the spot where I need to enter them. The part I'm not sure about is whether the custom mime types field is an addition to the current mime types or a replacement list. I couldn't find anything in the documentation that supports either option so I figured I'd ask here. Does anyone know if that field just needs the new mime types or a full list?
