I have been trying to fix this for days.
I always used the custom "post-name" permalink structure and everything was fine. Suddenly when I tried to click "previous page" - it directs my site to /page/2/ but it goes to a 404 page.
When I change the permalink structure to "default" it corrects this problem but I want to be able to use the custom permalinks because everything is already pointing to them.
I saw some people had luck when they changed the number of posts per page, but it does not make a difference for me. I have disabled all my plugins. I have tried deleting my .htaccess file, changing the permalink settings, and letting wordpress re-create the .htaccess file. I've tried a variety of fixes (adding/removing code from the .htaccess) from other wordpress forums. Nothing has worked for me.
My site is http://www.sketchbookcloset.com
My .htaccess file looks like this
# BEGIN WordPress
<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Please, I am desperate for a solution.
Thanks so much.
