Basically what I've written in the title.
I'm using a custom permalink structure: /%postname%/ as this provides an SEO friendly URL. However, when I click on an item in the portfolio I'm getting a 404 page not found error.
I've checked the URL and the theme is generating the correct URL, e.g. http://www.mywebsite.co.uk/portfolio/my-portfolio-item/ but it's not displaying the page. Even when I try and view the portfolio item directly from the Wordpress admin 'view portfolio entry' button it goes to an error page.
If I use the default permalink structure then it works, but I don't want to do this as it's rubbish for search engine performance.
Can you provide an SEO friendly permalink structure I can use? This theme is pretty useless for me if I have to resort to the default permalink structure.
[update] By hitting the 'save' button a couple of times in the permalinks section I can now see individual items when I click on them. However, now the pagination isn't working. Urgh. There's something amiss here somewhere.
