The discussion revolves around Blank topics after import. fbjerggaard reports that after importing data from Vanilla, all topics are blank, although the reply counter is correct and posts can be scrolled through. The issue is accompanied by JavaScript errors, specifically Uncaught TypeError: Cannot read property 'split' of null.
Other users, including Falco and cpradio, suggest troubleshooting steps such as enabling safe mode, checking browser console errors, and verifying overridden settings. fbjerggaard shares screenshots of the errors and settings, but the issue persists.
After trying various solutions, fbjerggaard reveals that they are using several plugins, but commenting them out (except the Docker Manager) does not resolve the issue. However, in post 17, fbjerggaard discovers that the problem is caused by a broken plugin, specifically the discourse-plugin-shared-edit. dax advises users to check the plugin authors’ activity and update status before installation, as the problematic plugin has not been updated since 2014.
After importing data from Vanilla all my topics are blank. If I press the reply-counter (which is correct numbered) I can scroll through the posts, but the main content section is blank.
I get a bunch of these Javascript errors when opening a topic:
Uncaught TypeError: Cannot read property ‘split’ of null
I’m running Discourse commit a6ebe49 (newest upgrade available at the time of writing this)
Please let me know if you need any other information.
ITs clearly something about the import. What version of vanilla? The MySQL importer or the other one?
The other one. Vanilla version is 2.1.11
The topic contents are clearly there but just not shown correctly.
It also applies to the autogenerated topics made by Discourse on installation
Have you tried safe mode?
Tried enabling safe mode and disabling it all but still the same result - topics come out blank.
Check this screenshot:
If you press F12 to open the Dev Tools, and reload the page, what errors do you see?
I get a bunch of Uncaught TypeError: Cannot read property 'split' of null
What file is it referencing? A screenshot of the error would be helpful.
Please share a link to your forum.
Okay, and you said you are not running any plugins right and zero customizations?
Can you go to Admin > Settings and check the box Only show overriden?
I have a feeling you changed a setting to a bad value. But I’m not 100% certain which one.
This is the overridden settings:
I am using the following plugins:
- git clone GitHub - discourse/docker_manager: Plugin for use with discourse docker image · GitHub

- git clone GitHub - communiteq/discourse-adsense: Google AdSense plugin for Discourse forum · GitHub
I tried commenting out all those plugins (except the docker manager) and rebuilding the app but with the same result.
Did you make a backup and restore from the backup after doing the import? I know that is recommended to cleanup some lingering performance issues.
It was a brand new Discourse installation so I didn’t think of doing the backup thing, but i’ll try that next.
Seems like it was a broken plugin after all, specifically this one:
https://github.com/gnunicorn/discourse-plugin-shared-edit
The author of that plugin is lost in the space for a long time…
A suggestion: before installing new plugins check if the authors are still active here on meta and if the plugins are up to date. Tons of things have changed from 2014 (last commit of the plugin).
I usually do that, but must have skipped it with this one since I was surprised to find it being that old, But good advice nonetheless!
