We found a solution to this!
If anyone has this problem in the future, do not truncate your db tables. It happened to mess a lot of things up for us.
Our solution
- In https://[your Discourse]/admin/customize/themes/[your theme] click the ‘x’ next to all the assets
- Go to https://[your Discourse]/sidekiq/scheduler
- Run the following jobs
- Jobs::CleanUpUploads
- Jobs::PurgeDeletedUploads
- Re-upload your theme assets (we uploaded them manually in https://[your Discourse]/admin/customize/themes/[your theme]. Then clicked the ‘edit css/html’ button and saved some of the files with errors.
Thank you @zogstrip for all your help!
