Upgrade/delete plugin links missing

Hi all

So we have a custom plugin, and after uploading to OJS2.4.8, on the generic plugins page I only see ENABLE while the other plugins already there has enable, upgrade and delete options.

What’s triggering this behaviour? Is there a management page for plugin permissions or is it picking up the file permission from server?

Thanks a bunch.


Hi @Sean_Xiao_Zhao,

Does the plugin have an entry in the versions table of your database?

Hi @asmecher

We were finally able to check the database, and yes the plugin name does exist in the versions table.


Hi @Sean_Xiao_Zhao

At this place in the template the links upgrade and delete are added: ojs/plugins.tpl at ojs-stable-2_4_8 · pkp/ojs · GitHub. Thus, maybe you can try to debug, why is it not displayed for your plugin…
