HTML Or PHP

Don't worry, it happens all the time. It is your browser caching your old page and serving it up to you again to 'save time' - a Windows thing. Get used to pressing F5 and it will force Windows to fetch the page again and you will see your changes. That of course assumes that you saved your mods and correctly FTP'd the page to your host.

First of all please specify what type of fie you have uploaded. You can send me the file and specify what you want to change or do. I may help you.

Try refreshing or deleting your cache. It's likely that your browser has cached the old version and is showing you that.

Can you drop the link to your file that has been uploaded ? And also please cross check that the previous file has been deleted and replace the same with the file with a same name.

By the time you read this I expect you are now seeing the changes. My best guess is the changes are taking time due to the server doing other tasks and will get around to yours eventually or more likely something to do with cookies on your browser. Sometimes it is necessary to update your browser. I've tried closing it down and reopening and even deleting the history web pages and saved files under options in your browser. Hope that helps, now curious to see if the changes took?
