Somewhere along the line my tag / category links no longer point to posts. I have my permalinks set up as follows:
In my widget the tag cloud points to the posts as follows (say, for tagged posts with 'thisone'):
mysite/tags/thisone. However, this just brings up a 404.
Similarly for categories:
simply says page not found.
Can't find where this went wrong. Any ideas much appreciated. Thx.
