How To Fix 400 Bad Request Error!
A quick tip on fixing 400 bad request errors caused by the Classic Editor in WordPress.
Last Update: March 25, 2019
Just a real quick one today. I read a blog or question yesterday in regard to a member having the same problem as I was and how to fix 400 bad request error which was occurring on our sites.
I can’t for the life of me find the question again to respond on it but I wanted to say a huge thank you to Marion Black for her suggestion on that post and share with you what worked for me.
Edit: Thanks again to Marion for providing the link to the original blog from Gordon – check it out here:
I run Thrive on my sites but there was another member who wasn’t and was having the same bad request error, so it’s not just Thrive and seems like it can be any theme.
After following Marion’s suggestion I started disabling and removing plugins to see what didn’t play well with my theme and site architecture.
As it turns out I believe it is a clash between the Classic Editor plugin and some themes.
After removing Classic Editor yesterday I have had no more bad error requests on either of the two sites. My third site which I had not downloaded Classic Editor on never had the bad request errors occurring.
So once again thank you Marion for your speedy suggestion, it seems to have fixed my problem, and hopefully others who have this same error may find this blog and can try this fix for themselves.
