I have difficulty to install the plugin Docs Viewer. I already disactivated PDF embed plugin not to have any conflicts. Furthermore, I tried to download both versions which are available, but both cases I have an error 404. None of the plugins that I have causes me this problem, so I am in a conflicted situation. I was wondering if there is someone else who has this type of issue. As well ,I tried to troubleshoot with those websites and tried everything that is written there ,but nothing helped .Here the following: Troubleshooting - Omeka Classic User Manual.
Thank you in advance,
