autoshutdown - plugin no more showing in OMV webgui

Hello, i have used autoshutdown plugin succesuly in omv 3 and 4 for years.

A few days back i installed omv5, upgraded to 5.5.20-1 and autoshutdownplugin was working correct with plugin version 5.1.3

Since today i can't open / see the settings windows of the plugin (now version 5.1.5) in the webgui of omv.

If i select autoshutdownplugin just nothing happens. But in dashboard the plugin is still shown up as activated and running.

So i tried to uninstall the plugin via webgui and installed it again. Now in dashboard its shown as not activated and not running and i am still not able to set up the plugin in the webgui.

So i used a filemanager to manually activate and set up the plugin, but its still shown as nt activated. i have added a screenshot and the (manually edited) config file.

Hello, yes i cleared the cache of my chrome browser multiple times, because running omv5 sometimes gives me some weird problems in webgui. After clearing cache it was working again. But in this case this seems not to be the problem.

Anyways, i again deinstalled the plugin, restarted omv again cleared browser cache and installed it again. Now its again working. Thank you you the fast response
