I am guessing, you just migrated your blogger blog to wordpress.
M=1 is one of the common problem bloggers face when they migrate their blog from blogger to wordpress.
I incountred the same problem a few days ago in one of my client’s site.
His blogs have redirect errors in the search engine console, you might be facing the same problem.
Blogspot uses m=1 to differentiate desktop users and mobile users.
And this problem can be in a different form in your blog like &m=1 or ?m=1.
So in this post, I am going to show how to solve the m=1 issue in your wordpress blog.
You can solve this problem by installing a redirect Plugin.
But I will show you a simple and step by step process to solve this without adding a plugin.
Here you go…
How to solve m=1 redirect issue in wordpress
Step 1: First of all log in to your Cpanel of your web hosting
And open the file manager
Step 2: Now, find out .Htaccess file in your file manager
( in some web hosting, this file can be hidden so first check to show hidden files )
Mostly it will be inside Public_html >> .htaccess
Step 3: Here click on the edit file,
This will open a window where you will find some text like the image below.
Step 4: Find out the # Begin WordPress

And paste the codes given below
#fix blogger m=1 issue in wordpress
RewriteEngine On
RewriteCond %{QUERY_STRING} m=1
RewriteRule (.*) /$1? [R=301,NE,L]
#fix blogger m=1 issue in wordpress ends
Step 5: Now click on the save button.
Here you go, You have successfully redirected m=1 URLs to the appropriate page.
If you also having the same redirect issue in the search console then save the codes and start validation.
This will solve the redirect problem.
