Otto Rocks! I read this thread and did all of the suggestions as he detailed, however, I still could not get it. I sent Otto an email and within a few hours, the issue was resolved.
The fix is this straight from the mouth of Otto:
“The problem was mod_security. Adding the .htaccess fix as described in
the sticky fixed it.”
I tried to make the htaccess file but didn’t do it correctly. I now know how and want to share it with everyone.
Simply create the .htaccess file just like Otto says. Use a text editor or Dreamweaver and put this code in:
<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
Save the doc as .htaccess and upload to your server in the wp-admin folder. Simple as that!!
Thanks again Otto, you are the best!
