The cause for missing image and JavaScript error as written before regarding Oracle Application Express Missing Images And JavaScript Error was the wrong image prefix.

The correct installation should have “/i/” instead of “/apex/TEMP”.

http://127.0.0.1:8080/i/javascript/apex_ns_3_1.js
http://127.0.0.1:8080/i/javascript/apex_get_3_1.js

Thus to correct this problem the prefix image should be corrected. It’s good that Oracle Application Express comes with Useful Oracle APEX tools just to do that.

After using reset_image_prefix.sql to update the image prefix the images that are missing now shows. Trying to login the administrator or developer page also now works. If you still experience some problem maybe the cause is different one. Kindly drop a message if you have any issues with this.
