I've changed my permalink structure to /%category%/%postname%/
However, the majority of the site uses Pages, not posts. Every time I click on a page link the result is a "500 server error"
Have updated the .htaccess file with the code generated by WordPress. This is the only code in the .htaccess file.
Have spent the last two days googling and trying to find related posts here.
Have studied the permalink pages in documentation, but can't seem to get it. Like this example:
Permalinks to pages don't work If you've tried to navigate to a newly created Page and encounter an error, you likely need to update your Permalink structure. Remember, each time you add a new static Page to WordPress, new rules must be generated and updated to .htaccess (WordPress 1.X) or to the internalrewrites array (WordPress 2.X).
My pages aren't new, they exist. This explanation doesn't say what else to do with the structure, nor does it explain "internal rewrites array." A search on that phrase points only to that page.
Any help is greatly appreciated!
*edit to get rid of horizontal scroll bar*
