This is still happening, although not all the time.
Different links, not always the same ones.
When it does happen, 2 things occur :
1. the URL in the browser displays the correct URL.
2. the page being displayed is a different page, and this can be any page in the site, usually one that has already been clicked.
I noticed this initially when clicking on a dropdown link on top of the submenu - the submenu page would appear, not the dropdown.
That doesn't happen anymore though.
Maybe this is a permalink/htaccess problem?
The permalinks are set to custom > /%postname%/
Here is the htaccess :
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
This site was set up in 2.8.6, then updated to 2.9 - which did not fix the problem.
Can anyone throw any light on this?
Thanks
