How I Solve HTTP Error When Uploading Images in WordPress

Another case study and experience-base post by ADD (did you already read ADD's about visual and text editor not showing in wp-admin?) Migrating to Wordpress given us some issues, but we think wordpress is still the best blogging platform (yet).

For about 5 days I've been frustrated not able to upload images in Wordpress because of its "HTTP Error." annoying message.

Way 1

Go to the image which you want to upload to WordPress.
Just Rename it, i.e. remove the old name and replace with a new unique name. (Don’t afraid, for better SEO, you can change the image name after uploading to the WordPress Library)

Result: Not working :(

Way 2

Edit .htaccess file and add following lines of code:

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

or putting this line in very top of your .htaccess file (tried this and my blog just went down):

AddType x-mapp-php5 .php

Result: Still not working...

Way 3

Changing Wordpress' size limit of file uploads at wp-config.php. Add this line:

define('WP_MEMORY_LIMIT', '128M')

Result: Still not working...

 

Way 4

Installing No Flash Uploader plugin.

Result: Still not working...

Way 5

Modifying file/folder permissions. In this case, update the wp-content/uploads folder's permission to at least 744 or 755

Result: Still not working...

Last Way

Honestly I already give up before I try this. Never think of it because it was too simple and I thought that won't solve the problem. All I did is deactivating WP Smush it plugin and then image upload works fine. OMG. Hope this helps.
