Application Express 3.1 Upgrade Missing Image And Javascript Error Solution

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.
http://127.0.0.1:8080/apex/TEMPjavascript/apex_ns_3_1.js
http://127.0.0.1:8080/apex/TEMPjavascript/apex_get_3_1.js
http://127.0.0.1:8080/apex/TEMPjavascript/apex_get_3_1.js
http://127.0.0.1:8080/apex/TEMPjavascript/apex_builder.js
http://127.0.0.1:8080/apex/TEMPcss/apex_3_1.css
http://127.0.0.1:8080/apex/TEMPcss/apex_builder_3_1.css
http://127.0.0.1:8080/apex/TEMPhtmldb/apex_logo.gif
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
http://127.0.0.1:8080/i/javascript/apex_get_3_1.js
