WordPress – Adding media leads to 404 error page.

October 6, 2015

Tried the below solutions to fix this problem.

 

1. Adding the below script in your htacces.

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

Source from WordPress

2. If not try contacting the hosting company to lift the security issues in your site. After working on this for 2 days, this one fixes it.

Have your say
