What is the problem?
Installing a plugin in plugin manager causes the info message to say that it installed unknown. Rebooting doesn't show any sign that the plugin is working, especially checking under the plugins tab where the plugin is no where to be found.
What did you already try to solve it?
Tried to run in safe mode, didn't work, tried to upload from file, installed but didn't work, tried URL, installed but didn't work, so same outcome every time.
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
No, but I noticed that the info message showed the name now, aka octorelay, but the plugin still did not work.
