Any idea what causes this? Never had it happen before. Happens when trying to install from any source.

I think this one solved here :slightly_smiling_face: [תמונה] FKB Pro - Social theme Theme Hello wave Is this your fork? https://github.com/GitHubQueenn/fkb-pro-theme2 It seems you created a stylesheets folder which duplicates the scss folder files. This cause the problem because the files duplicated and it tried to import from both folders. If you want to make changes on the style then please create a new theme component or change it in the scss folder or you can use stylesheets name too for folder, but not both. But it is better to keep scss as used by the main repo.

Failed to process hijacked response correctly : ActiveRecord::RecordNotUnique : PG::UniqueViolation: ERROR: duplicate key value violates unique constraint “theme_field_unique_index” DETAIL: Key (theme_id, target_id, type_id, name)=(50, 5, 1, common/fkb-c-alternative-voting-category) already exists.

Ah, this seems similar to an issue I already reported then: [תמונה]Failing to add a theme permanently prevents that theme from being added Message Failed to process hijacked response correctly : ActiveRecord::RecordNotUnique : PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_child_themes_on_parent_theme_id_and_child_theme_id" DETAIL: Key (parent_theme_id, child_theme_id)=(50, 35) already exists. Although in your case it looks like the theme ID it’s trying to use (50) is already in-use, instead of the parent-child link like mine was. Did you add a theme earlier that failed for any reason before the 500s started?

So, the original theme I use was on a GH repository. GH messed with the account I had it on, so I put it on another account and tried uploading it and then was getting this error.

So is the theme already on your instance? If that’s the case, does removing the old one help?

Well, I’m afraid to remove it since this one won’t install and then have no theme at all, haha.

Ha, no I completely get that. Just for a sanity thing, could you try renaming your current theme, and then re-import the new one? (I don’t expect this to change anything, but it can’t hurt)

Last idea before I leave this to someone who knows more than me, could you try renaming the theme in the theme’s about.json?

Yeah, same issue. So weird. I guess the 500 Error issue you got in January wasn’t resolved then? Or is there any way to just change the theme ID? I would’ve thought Discourse would automatically make that happen on import so that something like this doesn’t happen Oh wait, in the error log, it looks like everytime i try to upload it and it fails, it’s trying 1 number higher on the theme_id part of the error. hmmm

Could you check /logs after trying to add one?
