Ok, I will try to be clearer. When the Tooltipy plugin is activated (and only then) the Buddyboss plugin does not work properly. Buddyboss has a messaging feature whereby you can send messages to other users of the platform. These messages allow for attachments. When Tooltipy is activated, you can attach documents to a message, you can see the file, but you cannot see the file content, neither as a sender nor as a recipient of the message. Here is a screenshot https://bit.ly/35yMZqK. The relation between your plugin and this event is strange, but is a fact.
