- It is not possible to import from TiddlyWiki's on servers which are not CORS enabled. Popular sites such as TiddlyTools are currently not CORS enabled. Fortunately this is fixable - webmasters can enable their sites to be CORS enabled by following the instructions here and if a website is not CORS enabled you can e-mail the owner to tell them the problem
- Some browsers will only allow you to import from TiddlyWikis in the same directory as your TiddlyWiki. If you use Chrome you can enable this by modifying the Chrome shortcut to include the following parameter
--allow-file-access-from-files
- Note some browsers, notably Opera do not support import / upgrade in any form.
