Cannot upload file after upgrade

Permalink
Recently I updated from version 5.7.5.13 to 8.5.2. I am now not able to upload PDF files. Possibly other file types as well, although I CAN upload .jpg files of similar size just fine.

In the UI after choosing the pdf file, a green bar grows across the box, then turns to red. When I hover over the box, it turn red with the message "Unable to find the specified folder". Also in dev tools, the ajax request returned as status of "422 (Unprocessable Entity)"

A few of the things I checked after searching this forum
- The size is around 2 MB, well below the PHP limits I have set.
- my application/files folder has 777 permission

Try renaming the pdf file to remove the dot in the file name.

That was it. I removed one of the extra periods and it worked. Odd, that it allows some periods in the name but not that one... maybe the number of them, or location is the issue. I could do some testing I guess, but I'll just be sure to not have periods in the name moving forward.

So I was able to get a file uploaded yesterday after taking out one of the periods. Today I'm getting the same error trying to upload a PDF without any periods. It did have a space in the name so I removed that too and made sure it only had letters in the name. Still no luck. Any other ideas what may be causing this issue.
