Docman FILEMan.zip

Dear Mr. jhoan, good evening. I have the following operating system: windows 7 ultimate, joomla version 3.8.1- I tell you that since you introduced the version 3.1.1 of Fileman.zip I have upload problems. After installing fileman 3.1.1. and clicking on the upload command will not work, everything is blocked, and if you uninstall the Fileman 3.1.1 program again. and installing a previous version of fileman everything returns to running regularly. Could I know what the problem is? Thanks and good evening, Ing. Umberto CALABRESE
