https://cakespirit.co.uk/ has been going for some years. No problems at all. Yesterday my client said it had stopped working. An indeed it was just generating a 500 server error.
To check the domain I removed the .htaccess file and put up a simple html test. It connected.
So I figured it might be a corrupted .htaccess file, so I experimented with various versions of that.
Nothing worked so eventually I just ran admin/install and after that it was all there again.
However, the navigation was in wrong order - easily fixed, but most importantly, the blog tags do not work. Search function does but not tags.
How did it get broken and how can I fix it. Any ideas anyone?
