Question

We moved over the TWiki system from one machine to another. The problem is the following:

1. Change a page (like add the word test)
2. preview the page : the change is there (test is there)
3. hit Save Changes
4. change is there (test is there)
5. Hit edit
6. change is gone (test is missing)
7. go through the whole process above with "something else" instead of "test"
8. when you hit edit you see "something else" instead of "something else" missing
9. add in "ok"
10. go through the whole process again above until you hit edit to see the "ok" added in. Notice that "ok" is not in there.

It seems like some changes are saved / kept and some are not. The change appears to be there instantly. However, when you hit edit it the change may disappear. The workaround is to keep saving material to TWiki and checking the change using "Edit" until the change finally takes / saves, but that is painful. It reduces the chances of Twiki being used much. Did we miss a permission setting or is Mac OS X Server 10.2 the problem or something to do with the Version Control System or .... what? Thanks.

Not yet an answer

• Are you sure it's not a problem with the caching of the pages by your web browser??.
• Have you tried taking a look at the topic text file itself after a save?
• Is there any error reported in your server logs, or in the twiki error logs?

. Browser caching is the problem. For those who want to know more see BrowserIssues and search for Caching -- MichaelFinney - 15 Oct 2002

Yes, this is browser caching related - sounds like RefreshEditPage, where the symptom is that the second edit on a session 'forgets' the data you just added. This is easily fixed with a patch available on that page - or you could upgrade to the TWikiBetaRelease.
