I have installed the plugin, and the display was not clear and was taking the background color, so wanted to de-activate and delete the plugin.. But the below was the error.. Could not find any errors log, so had to contact the server provider to solve the issue and delete the plugin.. I would recommend plugin for developers, but not for new people like me 🙂
