Page Cornr plugin not working in Internet Explorer
After nearly pulling my hair out trying to get one of the few WordPress page corner plugins to work, I finally managed to get one working. Yay!
I used Page Cornr and while it worked okay in Firefox, when I checked IE it wasn’t there. 
I searched and searched and eventually realized that the theme the site I installed it on didn’t have a doc type listed in the coding.
I added in the following line:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
and VOILA! the plugin instantly appeared in IE.
FYI: This line goes in your header.php file – right BEFORE the first < html > tag. Some themes include it, some don’t.
Thought I’d pass on the tidbit to anyone out there who may be experiencing similar issues.
Hope it saves someone time, and hair
