Submitted to Community Chat

heyi Cant submit my trash to treasure project, it says error every time i try and upload my photos, ive tried changing the size and everything but still nothing. One attempt took my photo but then after everything was filled out and ready to go the save button wasnt highlighted and i couldnt save it. Ive tried 3 times and still no luck. Is anyone else having the same issue or know what i might be going wrong?
