what exactly happens to the hyperlink ? Can you show me a before and after.. Also - are you using relative or absolute hyperlinks ?
also - a little information about what the hyperlink is going to will help
Are you using relative or absolute values for the hyperlink ?
it's a big different for when you migrate your site to another computer/server etc..
Relative links will point to a page which is relative to the page that contains the link - for example - if the page was in the same directory and it was called default.html you can call it simply by putting ./default.html
Absolute is where you would point to the directory structure and location of the file.
I suggest you read the following article for frontage developers. it's not long but it's useful -- https://msdn.microsoft.com/en-us/library/aa155920(v=office.10).aspx
I would be glad to help. To better understand how your links are defined, can you upload one of your web pages to http://www.wikisend.com and reply to me with the upload link so I can take a look? I suspect you are using absolute local file system URLs in your web page and that is causing the problem, but it could be a number of things depending on how you set up Frontpage. Once I am able to view the source code of your page I will be able to identify the exact problem and provide a solution for you.
If you are having trouble uploading your page via my previous suggestion, let me know and I can walk you through the process.
If you are having trouble with wikisend, you could copy and paste the source code of your web page into http://www.pastepin.com and hit the Create New Paste button, then provide me the page link that is created and I can look at your page that way. Let me know if you are having trouble with either of those methods and I can walk you through it.
When you have a chance, please reply on the question page to let me know the status of your problem:
