Title: Permalink issues – 404 errors and out of ideas Last modified: August 21, 2016 --- # Permalink issues – 404 errors and out of ideas * [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/) * Hi, * I have had my blog up and running a few days now, all going smoothly until I tried to change my permalinks for SEO, as the Yoast plugin advised. I’ve selected the ‘month and name’ setting. * I have modified my /usr/share/wordpress/.htaccess file to what WordPress admin panel told me to. It still couldn’t write to it even though I resorted to 777 after it kept failing. This in turn makes me doubt whether I’m even using the right file although it’s the only one. * I have mod_rewrite installed and running with apache2, which I have triple checked with ‘a2enmod rewrite’ * My .htaccess file is (as directed): * ``` RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] ``` * Whenever I go to a post now I get a 404, this is the apache log snippet: * [Tue May 07 18:48:53 2013] [error] [client 5.65.18.60] File does not exist: / var/www/wordpress/2013, referer: [http://engineers-brain-dump.co.uk/](http://engineers-brain-dump.co.uk/) * I also get: * [Tue May 07 18:48:44 2013] [error] [client 5.65.18.60] PHP Warning: constant(): Couldn’t find constant WP_CORE_UPDATE in /usr/share/wordpress/wp-admin/includes/ update.php on line 33, referer: [http://engineers-brain-dump.co.uk/wordpress/wp-admin/options-permalink.php](http://engineers-brain-dump.co.uk/wordpress/wp-admin/options-permalink.php) * I’m pretty lost now, and it’s my first site so I’m new to wordpress. I’ve read loads of forum posts but can’t find anything I haven’t already tried. Any tips? * Cheers Viewing 14 replies - 1 through 14 (of 14 total) * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729556) * [http://engineers-brain-dump.co.uk/](http://engineers-brain-dump.co.uk/) is this your url seems as if is working fine on default setting. * Thread Starter [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729557) * Yeah I changed it back to default so I could edit some posts. I’ll change it back to broken for a while if you want to see it break. Any post or category links break and bring a 404 error. * ***EDIT*** * I’ve set it back to ‘month and name’, click any category or post and it breaks although the home page works. * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729561) * Where did you add that custom permalink did you use the one in list in Settings >>>> permalink if so looks like there must be problem on your settings on server as .htaccess file rewrites the url. when change to default .htaccess does not rewrite url. * Thread Starter [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729617) * I used the setting ‘month and name’, and then copied the modification to my . htaccess file like the admin panel told me to. It couldn’t write to the file so I did it manually. Restarted apache2, made sure mod_rewrite was running and bam, 404 🙁 * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729660) * What ever the problem is with your .htaccess file or Mod_rewrite * Thread Starter [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729668) * How can I rule out either? Any ideas? If it’s taking me to the permalink and not finding the file which part is to blame? * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729673) * That sounds like an issue with the server – maybe a problem with mod_rewrite. * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729678) * If you copied the code that wordpress gave you as is in .htaccess file then most likely is Mod_rewrite problem.Have you tried any other permalink settings like postname * Thread Starter [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729684) * I’ve just tried postname, and I get exactly the same thing 🙁 * > [Tue May 07 21:24:00 2013] [error] [client 5.65.18.60] File does not exist:/ > var/www/wordpress/how-to-make-your-own-button-in-phpbb-reply-editor * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729690) * That means is diffidently problem with server settings for Mod_rewrite. * Thread Starter [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729693) * Ok – thanks 🙂 * I’m just looking up AllowOverride etc, my server’s httpd.conf file is blank – should this be the case? * Thread Starter [tom0311](https://wordpress.org/support/users/tom0311/) * (@tom0311) * [13 years ago](https://wordpress.org/support/topic/permalink-issues-404/#post-3729699) * I’ve changed the file /etc/apache2/sites-enabled/000-default, all references to AllowOverride are now ‘All’.
