This is very strange. I used Inspect Element in Chrome to see what CSS rules were being fired by a portion of a page of a site using the Prospect theme. I downloaded that CSS file, made some changes, and uploaded it again. No effect on the page. When I Inspect Element again, the portion of the CSS showing in the display box does not reflect the changes I made, rather it shows what was in the original CSS file. I went back and added rows of /***/ comment lines, then uploaded again, and inspected element. Nothing shows, and the line number of the rule fired was the old one even though I added that comment line above it to change its position in the file.
I've checked, no cache plugins installed on this site. I've flushed the cache in Chrome, switched to two other browsers, re-downloaded the CSS file and looked at it to insure the changes were indeed uploaded, and even changed themes to a different one and back again, still no sign of the changes I made to the CSS file.
Is there some way to force a theme to refresh the CSS files it's reading? How can this happen? I'm baffled.
Thanks in advance.
