Hi
I tried to create a plugin and then delete the one file that was in
the plugin. Then I recieves an error ticket shown below.
I created a file with name plugin_init/default/index.html and then
clicked on the init plugin in the bottom of the init screen, looked at
the file and then deleted it.
Then it crashes and I think it has something do with that the plugin
disappears when the last file has been deleted but the admin still
tries to show all files that contains to the non existing plugin.
