In my IDE, there is no code, but it shows “Hello” in a purple background. I have saved my code by adding a character and saving, then deleting that character; no luck.
In my PHP workspace c9 looks into the
workspace folder for the index file. Perhaps you are placing files in the wrong folder? Where is your index.html or index.php located?
I don’t have either. Sometimes when I run my code, it works. Other times it doesn’t.
