Have you tried updating your permalinks? If not, log in to your site as an admin and then go to Settings > Permalinks and click Save Changes. Moreover, how are your permalinks structured? For example, a common way to set them is Day and name.
Just in case, also.
I’ve had and seen that issue randomly here and there, so keep this snippet of code if needed.
If even when you change permalinks structure you have the same error to open posts, check by FTP if you have an .htaccess file at the root of your wordpress installation directory.
If you don’t have one, create it.
And check if its contents are:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
This is the default structure, I occasionally had to restore it to fix this error.
Sharing the code just in case 🙂
Randy – thanks for that i/p. Yes – the permalinks are updated. And they’re using the post name structure – exactly (I thought) as I’m successfully using them on another wordpress site :-(.
Sabinooo – thanks for that tip. I’m afraid it’s maybe time for me to call in my web design people to assist…
Well, if you want, Bren, if you want.
I’m not sure where you gave up, is this .htaccess snipped thingy something you tried but doesn’t work, or something that you don’t understand and on which you have given up ?
If you gave up, if that can reassure you, it’s no big deal. As long as you have what we call FTP access, it’s a matter or 3, 4 or 5 forum post replies to get you through it.
But no pressure, if you can make others work on it, heh, that’s less work for you 🙂
Sabinooo’s i/p prompted me to take another go. I got ftp access, retrieved the .htaccess file, and its contents looked like this:
# 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
Comparing it to Sabinoo’s suggesteed code, I saw that I needed to remove the first RewriteRule command. I did so, uploaded the changed file, and the symptom has remained :-(.
