landing pages keep redirecting to blog 404 image oops page not found

Greetings!

Here’s our canned reply for 404 errors:

To fix 404 or A/B testing issues follow these steps:

1. From your WordPress Admin Dashboard, Head into Settings->Permalinks and re-save settings and re-check.
2. Manually view .htaccess file (in the root directory of your wordpress install, aka the folder with the wp-content and wp-admin folders located in it) and make sure #wordpress rules are on top and recheck (see below for example).
3. If solutions 1 & 2 fail then head into your wordpress base directory and delete the .htaccess file and then re-save permalinks.
4. If solution 3 fails then disable all other plugins and re-save permalinks and recheck the landing page URL.
5. If solution 4 fails please post the contents of your .htaccess file here for review.

Your htaccess file should look something like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

RewriteCond %{QUERY_STRING} !lp-variation-id
RewriteRule ^go/([^/]*)? /wp-content/plugins/landing-pages/modules/module.redirect-ab-testing.php?permalink_name=$1 [QSA,L]
RewriteRule ^langing-page=([^/]*)? /wp-content/plugins/landing-pages/modules/module.redirect-ab-testing.php?permalink_name=$1 [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

</IfModule>

# END WordPress

What if the page not found error only happens when I’m adding an image to a page or post? I can publish them fine without any image, but fails everytime I try to add one. Also happens when I edit the theme or plugin using the online code editor on WP. Clicking save will send me to page not found error page.

This does not sound like a normal plugin error. Most likely there is a theme or plugin conflict causing this behavior and you’ll have to root it out.
