Thanks for the suggestion.
I tried that, but it didn’t work for me.
I always get a WordPress page saying:
Error 404 – Page Not Found!
Whoops! Something broke. Please try again!
Here is the current content of my .htaccess (my “app” is called “keyword”)
# .htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^keyword/([^/]+)/([^/]+)$ /keyword/?a=$1&b=$2 [QSA]
RewriteRule ^keyword/([^/]+)$ /keyword/?a=$1 [QSA]
</IfModule>
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I am still looking for a solution, …
