Hi @monirehbastami,

Perhaps you could provide the link to the where specifically you’ve downloaded the plugin from Github? Also, can you verify what specific version of OJS are you using (e.g. you say 3.3.0-4, but do you mean 3.4.0-4?) - please indicate this in your posts, as it is important for troubleshooting. Also, knowing what version of OJS you are using and what version of the plugin is important, because some plugins have not been tested against particular versions of OJS and may not work.
