Admin area menu and posts page not working (after activated AddThis)

@bluemad: Do you notice any javascript error in console? If you can provide access to your development site, I can assist you.

Srijith V. Nope. If you can give me your contact info, I can give relevant info.

@bluemad: you can reach me on srijith[AT]addthis.com

TypeError: a is undefined this is message from console

Well, I found the issue. It generated this htaccess code. After I removed it, now everything OK.

# Redirect to www domain
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mydomain.com$
RewriteRule (.*) https://www.mydomain.com/$1 [R=301,L]

Any solution?

@bluemad: AddThis plugin will not generate any htaccess code. It might be by another plugin which you have activated at the same time. Do you have a suspect? I can check if you can provide access to admin dashboard to srijith[AT]addthis.com
