I started deactivating plugins and the issue turned out to be the WP Super Cache plugin – once that was deactivated, the site worked again.
I am having the same issue, but I have blog that has been up for months. Since upgrading to 2.9.2 this morning, I can access the admin area and even preview posts, but all attempts to view the site result in:
“500 – Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.”
I can, however, view pages if I add “/index.php/” before the permalink.
I’ve had my host look at it and even update the rewrite module, but to no avail. They say there’s no permissions issues.
Here’s what I’m running on: PHP 5.2 and MySQL 5.0, but we are not using apache to host blog, it’s running on IIS 7, with rewrite module.
Any suggestions/ideas would be greatly appreciated.
