Using Google->More tools->Developer tools (Ctrl+Shift+I) a 404 error was found with additional script errors due to the the timeline window not populating correctly.
I set up some a sandbox for testing and found the blank window usually occurs when running https. I was unable to determine the root cause but I found simile-timeline uses a "dummy" history.html file which is called from simile-ajax-bundle.js.
A history.html file is included with simile-timeline but the line above does not specify a path and uses underscroes in the file name. This must have been an oversight because every example on simile-widgets.org has a 404 error except Compact Painter which has a 410 errors due to missing graphics files.
To correct this problem add the path and change the file name in simile-ajax-bundle.js on line 1967 as shown below.
Code: Select all
There are some differences in the dates between 2.3.0 and 2.3.1 when used with TNG.
Version 2.3.1 is available on Github with a change file stating "Version pre 2.4.0". The download below contains the library files and is configured to use local resources instead of static.simile.mit.edu or api.simile-widgets.org. The files use the correct file name and path for history.html, which should solve the blank screen issue. You can view version 2.3.1 on my genealogy website.
The timeline_231.zip file can be used by anyone that wants to run timeline. All files should reside in the timeline_2.3.1 folder, otherwise you could have a blank timeline window. For instructions please check simile-widgets.org. Report issues or check pull requests on Github. The simile timeline user group can be found on Google.
Timeline 2.3.1 was tested on versions v11.1.3 and v12.0.2. (Timeline 2.3.1 does not work on TNG v10)
If you want to remove simile timeline dates use the MOD below. The mod does not affect TNG dates and is useful if you do not want to show simile dates in the timeline event band.
I modified the USA timeline events so images are in the event folder instead of the TNG img folder. Additionally images and text are centered in the bubble, as shown above.
