I install the opigno chat app, but get the error message as below: Opigno Chat App has missing depedencies (missing depedencies: ) How can I solve it? By the way, what is the real module name of opigno chat app? It seems not "opigno_chat_app". Thank you
That is very strange.
Please do the following, disable the opigno chat app as well as the drupalchat module. Uninstall both and remove both from the sites/all/modules folder.
Go to the apps page. and click install the opigno chat app.
