Need to ‘undo’ Go Live changes

I should preface this by saying I know very little about web development. I got overconfident and probably should not have used Go Live at all, and I have tried to fix the problems I caused on my own with very little knowledge and may have made things worse.

I was working on the site and the plan was to move it to . It seemed that using Go Live was a good idea. However, this was a very stupid idea, because the old URL was planned to be reused to make a blog. Not to mention, to move the site properly I needed to transfer the theme and activate it, and we have a single use theme license which is still activated on the old site, so I should definitely have dealt with that first.

Smartstagemom.com was the wp home and site URL, so when I made the Go Live changes I blocked myself out of my own WordPress admin controls. I can’t even run the Go Live plugin again.

Based on some frantic Google searches and 15 hours of desperate learning, I tried using Go Live on the new site to redirect aaronjjacobs.solutions/smartstagemom to smartstagemom.com. I tried using Chrome plugins to stop things from redirecting, and tested to see if the problems occured differently in different browsers or incognito windows. I tried using FTP to open wp-config.php and added define(‘WP_HOME’,’https://smartstagemom.com’);
define(‘WP_SITEURL’,’https://smartstagemom.com’)
I have also read this page: but could not really make sense of it.

None of these things have worked, and I’m sure the first few things I tried hurt more than helped. The most progress I have made was getting the site to stop redirecting and just displaying a 500 error. And no, I didn’t backup any databases because I have no clue how to and like I said I was overconfident when I decided to use Go Live.

Is there any way at all to fix this situation that I could try? Do I not even understand my problem to its full extent? (Probably) Am I the first person who has ever been this stupid?

I’m sorry. Please help me. Thanks.
