I have a website and my client wanted to add a sentence on all pages. I updated the template, when it asked to "update all" It 'updated successfully'. I haven't had a problem up to this point. It is in a template object so I can't update each page individually.
I had done a couple of things, added a sentence and changed the rollover color on the links. When I open the individual pages the rollover color updated but the sentence is not there.
When I click on the template in the Assets panel, it shows it correctly.
I am using CS5. I have also tried the site>advanced>recreate site cache. I have shut down everything and tried again, still doesn't work.
Have you tried opening the .dwt file and then selecting Modify > Templates > Update Pages? That often fixes a problem if the automatic update fails.
If that doesn't do the trick, as Ken Binney points out, it's necessary to see the code to see what might be causing the problem.
The website is http://rcottonlawpc.com, in the template (which sows correctly in the assets panel) after the "areas of practice" it is supposed to say "click on your area of need". I had typed that in just before I changed the hover over links to change color, so they would be aged at the same time. The hover links work, but the test doesn't show up on the individual pages in the code, just in the template.
"Click on your area of need" is in the Sidebar1, which is within an editable area.
I suggest that you make that an in-editable area (if you want the sidebar material on all the pages based on the template, it is the best idea).
Once you have done that, your template should update your pages appropriately.
