After uploading the module plupload-7.x-1.1.zip which was installed completely and successfully, I get an error message, when I click on configuration in the Admin menu.
The status report lists plupload as the module having an issue:
Plupload library Not Found
The Plupload library (version 126.96.36.199 or higher) is not installed.
Can you help explaining this or advice, how to move forward ?
