My main production site just started looking like this for all my categories. When you click on the category, you get this message:
Warning: main(./wp-blog-header.php) [function.main]: failed to open stream: No such file or directory in /home/hairstyl/public_html/index.php on line 4
Warning: main(./wp-blog-header.php) [function.main]: failed to open stream: No such file or directory in /home/hairstyl/public_html/index.php on line 4
Fatal error: main() [function.require]: Failed opening required './wp-blog-header.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/hairstyl/public_html/index.php on line 4
This just started happening last night and I didn't even do anything. HELP!!!
OK so I called my host and they corrected my site. Apparently, a hacker got into my site and there was something about a redirect. Everything on my site was screwed up. The only page that was normal was the main page. I have not upgraded this site yet and am still running on sempro: 5.0.2 and wp 2.3.3. The reason that I have not upgraded is due to fear. I guess I am going to have to bite the bullet. I am wondering if anybody knows if the fact that a hacker could have gotten into this site would be due to the fact that I have not updated. I am just curious. I see the sticky post about upgrading production sites and to create a mirror site but I am afraid that I would screw that up and have no idea how to do that. I am going to go running and try to work off some stress while I think about this.
5.0.2 and wp 2.3.3 should be fine. It depends on what permissions you had on your directories and files. If your index.php had 666 permissions someone could replace it.
