Question

About 6 months ago, I had a developer write a "fast save" option for my twiki. It simply skipped the "preview" button and saved directly.

All worked well for several months. Then we started seeing errors on saving. I've had a developer spend a lot of time debugging and he came to the conclusion that there's a problem with the webserver.

Since this was on a hosted server, we moved to a dedicated server. The problem continued.

We've done a fresh reinstall (several times, on both the old server, and the new one), and its still there.

We're not sure if our data is corrupted, or if the issue is something else. We're at wits end.

The error only appears intermittently, and particularly happens when editing different twiki webs - less so on the same web. Its almost like it just happens only once per session per web. We have heard of other users experiencing the same problem; yet there seems to be no documentation on this in the twiki support area.

This is the full error which appears:

Inproper use of the save script You cannot call this script directly, TWikibeta uses it internally. Some browser configurations occasionally send undefined data to the server. Don't worry, your changes are not lost. Just click the Back button on your browser and then try Save again.

The other possibility is an internal error in TWikibeta configuration, or that you did not have write access to the directory or file that was being edited.

Please go back in your browser and save the topic.

Answer

Not sure what might cause that. Time for some serious TWikiDebugging. See also ImproperUseOfTheSaveScript.

Alternatively, upgrade to the latest TWikiRelease01Sep2004 which has the direct save feature built in.

You're not the only one to encounter this, see ImproperUseOfTheSaveScript. It's critical to understanding this that you do what Peter suggests and check the Cairo version, and establish if the error occurs there as well.

We also need more detail on how this error arises. I for one can't reproduce it, and I suspect others can't either. So let us know the exact set of steps required to reproduce the error (ImproperUseOfTheSaveScript is rather vague)

I notice your installation is called "Twikibeta". Are you sure you are running 20030201 and not some subsequent beta?

Perhaps you can ask your developer to follow up on the questions I asked in ImproperUseOfTheSaveScript as well.

We have upgraded to the Cairo version of twiki, and this problem has not reappeared since we did it. The upgrade was non trivial, but seems to be working mostly ok now.

Thanks for your help and suggestions.
