TiddlyWiki Classic - Problem With Loading Downloaded File

[Mark Gerry]

I recently started using TiddlyWiki Classic and I've run in to a problem that may cause me a lot of work. 

For some reason when saving my file it didn't go straight to the folder of the TiddlySaver, it downloaded like any other file. So I have a Chrome html document called 'download' in my downloads folder. When I copied this into the folder with the TiddlySaver and tried to open it, I got a blank page, not even a new TiddlyWiki, just a blank white page. I don't know what to do, and I am relying entirely on you guys. I hope you can help.

Never met this problem. I tried TWC 2.8.1 on Firefox with tiddlyfox firefox plugin installed and it works perfect with the latest firefox version.

This behavior indicates that your copy of TiddlySaver.jar is not working properly.  There are several ways for this to occur: incorrect privileges for running Java applets, or a damaged TiddlySaver.jar file, or even a Java engine update (depending upon your OS and version).  In any case, when TiddlySaver.jar fails, TWClassic2.8.1 will fall back to using the browser's built-in "download save" handler, which creates the "download.html" file by default (note: you can change your browser setting to "always ask" when downloading... this will allow you to choose the name/location for the 'saved' file, rather than using the defaults).

Normally, the "download save" produces a complete copy of the current document, including all changes you have made during the session.  Check the size of the saved file... If it's 0 bytes, then the download save process failed (this would be very surprising!).

If the filesize is > 0 and the TWC file opens a blank white page, it usually means that an error has occurred during the startup initialization routines.  This can be due to any number of reasons... it might be a 'mangled' file, or it could be an error while processing the initial tiddler data, or invoking improperly installed plugins, or an error in the StyleSheet CSS, or ???.

You can check for any reported runtime errors by opening Chrome's javascript console (use ctrl-shift-J or choose Tools>Javascript Console from the Chrome "hamburger" dropdown menu).  If the console displays an error message, this may provide enough information to determine what is going wrong.

Even if we can't figure out what is wrong, if the file has some contents, then your tiddler data may still be intact, even if it doesn't display in the browser.  To confirm this, open your document in a *text editor* (I suggest Windows-standard WordPad), and look for <div id="storeArea">.  Everything following this line is stored tiddler data, encoded as HTML DIVs.  The store area ends with <!--POST-STOREAREA-->.  Assuming that the tiddler data itself isn't mangled, you can 'rescue' the data by copying everything from the opening storeArea div through the closing comment marker... then get a fresh, blank copy of TWC281, open it in a text editor, find the POST-STOREAREA marker, and paste your rescue tiddler data there.  Save and load that file to see if it worked.  If it does not work, then it means that the tiddler data itself is damaged (which could result in a startup error if the damage is in the code of a plugin tiddler).

If none of the above helps, then we'll have to dig a bit further.

enjoy,

I think you were right about it being a broken file. I decided to import use the 'import' option in backstage and got most of my tiddlers back. Two were missing, so I assume they somehow corrupted the HTML file. Unfortunately one of them was several hours work, but I'll manage. 

Thanks for your help.
