I accidentally changed the URL modifications under Settings, and crashed my site.
Now I have removed the Polylang plugin (through FTP) and made the site work again, but once installing/activating the plugin again, the erroneous setting I made gets activated again, and disable the site once more.
What can I do to remove any entries I have made earlier and to start from scratch?
I successfully set up the plugin on another test site, so I now know what settings I must use. Thanks ahead!
