Hello @UsmanMulla
I am sorry you are having trouble with you e-Portfolio.
It sounds like you may have created 10 pages in your Portfolio but may have missed a step somewhere when uploading content to them..
Pages are generally used to share content such as submissions and things you have done in Canvas. If you click into some of the pages you should be able to select the option for Edit This page. From there you can add content using the Rich Content Editor and such.
Without being able to look at your Portfolio, I won't be able to see why the content was not saved that you tried to add. After adding content to some of your pages, are you select the option for Save page? If the content is not saving, you could try clearing your browser cache and rule out that the cache is causing the content not to save. (For MAC and PC.)
HERE is a guide on how to preview a page within your e-Portfolio.
Keep up to date on this!
