I’m customizing the product page in the view.phtml file, The changes which I’m doing are not showing in the frontend. Even adding a <p> tag is not reflecting in the frontend. All the css changes are working properly.
Essentially, changes in phtml files only not working.
Try the following:
System->Configuration->Developerand turn onTemplate Path Hints– this will tell you which template file controls which block. Check you are editing the correct file. (note, this is not suitable for a production server/live site).
