Error in Uploading to MicrobiomeAnalyst for 16s rRNA analysis

Hello, I have previously been able to upload my files for analysis to the website previously but I keep getting an error screen the last 3 days. Is the website currently being updated? the same files work when being uploaded to projection with public data.

Hello, we are in the middle of updating our website. Could you please follow our post guideline to provide an example for the trouble shooting?
