Page Names appearing in small cases

Look for something like text-transform: lowercase; in style.css

I did find the line:
text-transform: lowercase;
in my style.css. But even after changing it to:

text-transform: capitalize;

it didn’t help. Also the way my themes call the pages in header.php is quite different. I don’t see any wp_list_pages function in it.

text-transform: none;

worked for me — clear your browser cache might resolve.

just for more information, the code

text-transform: lowercase;

can be found under the block

#nav li a{}

changing “lowercase” to “none” worked perfectly for me. Thanks for the tip!
