Converts https links to http links

[SimonSiefke]

When trying to insert https links in wordpress with this plugin enabled, https links are sometimes converted to http links:

https-link.mp4

I believe, the plugin tries to “fix” a spelling error when entering the https link which causes the https link to be converted to an (less secure) http link.

Perhaps it might be a good idea to not enable the spell checker for link input fields.
