If you have any difficulties with MultiMarkdown Composer, there are a few things you can do.
Use the search box on this web site or on http://fletcherpenney.net to search the best sources of information about Composer and MultiMarkdown in general. You may be able to find information relating directly to your problem.
Enabling the “Advanced->Troubleshooting” preference is not recommended during normal use, but can be useful when you experience problems. Currently it does the following:
Disables web view updating on iPhone and when the web view is hidden on the iPad — this is useful when you have an unusually formed document that causes the Markdown/MultiMarkdown parser to hang. This disables PDF generation, however, since that feature relies on using the web view.
Enables a feature in the Action Menu to export a list of all the titles of your notes, as well as their filenames. You can use this to sort through if some of your notes don’t seem to be synchronizing properly.
Future versions of Composer will use this feature to enable additional troubleshooting features.
If you get the message, “MultiMarkdown was unable to parse this file”, it means that something about your file was not quite “valid” MultiMarkdown syntax. MMD tries to process it for a few seconds, but then times out if it runs into trouble. Usually, this has to do with improper or unusual use of ‘*’, quotes, or apostrophes. Sometimes it can just be an unusual document that gives MMD trouble. If this occurs, feel free to post to the MMD discussion list to get help. This is not a problem with Composer, but rather that your document is not compatible with MMD.
