Wordpress 2.5 “An error occurred in the upload. Please try again later”

This was the other wordpress 2.5 issue I had.

This was on a live server and not local. I tried to upload an image and the image crunched ok, but I got this message when it was done. I think it has to do with write permissions but the solution I found was to add this to your .htaccess file.

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

That seemed to fix the upload issue but the next issue I had was when I tried to actually insert the image into the post, all I got was a blank screen from the media page.

After a few times of the blank screen I restarted firefox and now everything worked fine.

I guess the first problem affected the http state of the browser or window or something and the restart just cleared it all up.
