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 22.214.171.124 or higher) is not installed.
Can you help explaining this or advice, how to move forward ?
