When pasting text with a link to an internal resource, the manager url is prepended to the link tag. For example if the link in the copied text was [[~123]], it becomes /manager/[[~123]] when pasted.
Update: Upon further investigation, this happens in Chrome (78.0.3904.87) but not in Safari. I’ve not tested Firefox or Edge/IE yet.
I’d like to bring this thread back to life because it’s happening to me too.
When copy/pasting a normal link in the text editor, like: my-cool-cat
the full URL and manager directory is being added to the url, like: catsite.com/manager/my-cool-cat
rending the link useless.
Following more information through our support email, I’ve just released v3.4.2 with additional fixes around the manager url being added and making sure it is removed.
Please try it out and let me know if you continue to encounter issues with that!
