After installing WP Robots Txt, I noticed that once I pressed "Update" after any changes on the 2 websites I installed it in, I would get a blank page and I'd have to return to those pages manually through the URL.
Now it got worse, I can't access the backend of any of the sites I installed it in. If I type example.com/wp-admin, I get a blank page.
I believe I left the User-agent:* Disallow:/wp-admin/ and Disallow /wp-includes/ on the file.
Could that have caused it? Regardless... How do I go back to what I had before? I already ftp'd into the server and deleted the plugin files manually but I still get a blank page.
How can I fix this?
