Problem on submit Archon

Hi, i have a problem : when i submit e file version e libre office i have this errore: Invalid file extension (.ods). i have try with excel file and i have the same error: extension (.xlsx). What the problem? Thank you.

The new upload system is going live today (I made the announcement in the Prince list: www.vekn.net/forum/prince-list/75010-archon-1-5e-and-new-upload-system) Due to rights issues, it doesn't work right now. I'll keep you informed about the resolution. In any case, it should be ok after the maintenance scheduled on sunday, if not before. Prince of Paris, France Ratings Coordinator, Rules Director
