I have recently installed the latest wordpress theme 2.9.1 to a new web hosting package (FastHosts UK). I set up the blog following the 5 minute installation added all my content and every was fine.
I wanted to make sure that my URLs were SEO friendly so I went to custom permalinks and entered /%category%/%postname%/ and saved the changes. I visited my website and noticed that when I clicked any link on my site I got the 500 Internal Server Error page.
I removed the .htaccess and the site reappeared before doing exactly the same once I clicked on another link. I contacted my hosting provider and they assured me that the package that I was using has the ability to handle wordpress.
I have searched the web and tried all different things to get them to work inculding deleting and reinstalling WP on numerous occassions, populating content, not popualting content, changing .htaccess permissions, check mod_rewrite is on.
I do not know what else I can do? Any ideas...?
Help would be much appreciated.
