File Upload Hangs Indefinitely - Workaround
When uploading files to Tiki 9.4, the process will occasionally hang in the "Uploading file..." state.
You won't know it's hung unless you monitor the upload in an alternate way such as using Windows Task Manager > Networking. There you'll see that upload traffic initiates when you click on Upload File, but occasionally ceases before upload is complete. When that happens, the Tiki Upload File page will continue to display "Uploading file..." indefinitely until you finally get tired of waiting and realize that something is wrong.
Workaround is to abandon the current upload and start over, all the while monitoring via Task Manager or other software so that you can know if/when Tiki upload fails.
