Sometimes you might be trying to upload floor plan sketches and it is not working. You can select the files on your computer but the upload button does not work.
It turns out some strange characters in the file name, like an apostrophe or other characters may impact how our system recognizes the files. We suggest you name your files a consistent name, like the tour ID or street, such as
155888 first floor, 155888 second floor or 123main first floor, 123 main second floor
This will minimize any issues caused by the file names.
This also applies for photos, as we have seen some long, strange characters in the file names mess up parts of the photo system as well.
