Apliqo File Upload Error - Related to the Naming of the File

Hi All,

I have an interesting case. In our model the client uploads actuals with the csv files. And we are using the media upload functionality of the apliqo a lot. It is working well in almost all cases.

Today we have received an error like this.

When I was trying to understand the reason, I have change the naming of the file and tried to reupload, and it worked. Then I keep the existing naming and I just added one aditional character to the very end, and it worked again.

So I wonder if you have any idea why?

Thanks in advance
