Yesterday when I was trying to publish a post it was redirecting me to 404 error page. The problem was with only one particular page and it was some way related to the post content. I was able to save the post when I removed some part of the post. I tried a lot of things like
- Disabling plugins
- Activating the default theme
- Updating and reinstalling WordPress
- Rewriting htaccess and updating permalinks
Nothing helped, some of the threads on this problem referred to mod_security rules. The problem was due to the mod security rules. As my post had some strings that directly relate to security issues. These obviously triggered some mod_security rules I had to disable mod_security rules temporarily to publish the post.
This is what I added to /usr/local/apache/conf/modsec2/whitelist.conf, (location may be different in your case)
[code]
<LocationMatch "/wp-admin/*">
SecRuleRemoveById 300015
</LocationMatch>
[/code]
If don’t have the permissions to edit mod_security rules, ask your hosting support team to update them for you. You may want to show this post as reference to them.
this is good, thanks for good info. just learned something new with wordpress
Thanks so much for this info. Indeed I have been having this problem for weeks now, blaming it on my Internet service provider (until I tried updating from another provider). makes WordPress near unusable unless one sues a third-party editor, like Windows live writer. I wonder how my server provider is going to react when I spring this on them
They are going to reply positively, it’s possible to modify the security rules only for your domain.
I found that problem in my blog.
