Something really weird is happening on my website, there is an image that is not displaying!
The problem seems to be file extension. Theoretically, the file extension is .png (but it seems it is .PNG somehow)
Here is a screenshot

How this happened?? and How can I change the image extension back to .png??
I really don’t want to put .PNG on the CSS file!
Step 1:
FTP to server
Step 2:
right click on file and rename to pager_bg.png
Step 3:
refresh browser
Assuming your CSS has the correct value all will work as you expect now.
