I finally got around to upgrading from a much older version of WordPress to the latest. I followed all the detailed directions and, save for a few kinks, all seems to be fine. There are two issues, however, that I can't figure out.
1) On my site's footer, there is the following:
Warning: Invalid argument supplied for foreach() in /home/content/t/e/e/teeveesbella/html/wp-content/plugins/sem-theme/sem-theme.php on line 558
My theme began as an ancient Semiologic one from ages ago, which I customized almost completely back when I first created the site. Everything else in the layout seems to have made the transition to the upgrade quite well, so why is this weird error appearing all of a sudden?
2. Even more distressing is the fact that I can no longer edit posts or pages. When I try, it turns over to the edit screen but, before I can even do anything, it acts as if I've already hit "submit" and goes back to my website, as though I'd edited it successfully -- when, in fact, I never even had a chance to. Any ideas?
Thanks very much! Oh, my site is at http://www.eyeflashes.com, just in case that helps.
