When I drag n’ drop the translator-v2.0.3-1.tar.gz file (https://github.com/pkp/translator/releases) via the “Upload a New Plugin” interface of my newly updated OJS 3.1.2 instance (formerly 3.1.1-4), I get a notification saying “Plugin already installed, but can be updated to a newer version.”
However this plugin doesn’t seem to be installed. It is not in the Plugin Gallery (Generic plugin section), nor anywhere under my \ojs-3.1.2\plugins\generic directory and, as expected, the “Translate” tab isn’t showing either in the web interface.
Next, clicking on the “Save button” throws this message : “No file uploaded or invalid file type!”
(Formerly, I had no problem at all installing version 2.0.3-0 of this plugin for my 3.1.1-4 OJS instance going the same route).
How can I install the translator plugin or activate it (if it’s indeed already installed but not showing?)
