Error Loading Bricksforge Backend

Hi All,

We’re working on a client side who has Bricksforge Installed. It was previously working with no issues and an activated licence. However, in the backend Bricksforge Panels we get the following error and can not load any settings:

Failed to load resource: the server responded with a status of 404 ()

/wp-admin/admin.php?page=bricksforge#/:1 Uncaught (in promise)

  2. code: “ERR_BAD_REQUEST”

  3. config: {transitional: {…}, transformRequest: Array(1), transformResponse: Array(1), timeout: 0, adapter: ƒ, …}

We have tried uninstalling all plugins. Re-installing Bricksforge, Updating and/downgrading it.
However, it has not resulted in a fix.

I can not find any relevant forum topics. Do other people experience this issue?
How can we resolve it?

Thanks in advance!

I guess refreshing your permalinks should do the trick :blush:

Hi Daniele,

thank you so much for your answer. Unfortunately changing or flushing the permalinks through the means I can find online does not yield any effect.

When opening just the bricksforge backend page the issue:

vendors.js?ver=1751004214:2 SyntaxError: Unexpected token ‘<’, "<!DOCTYPE "... is not valid JSON at JSON.parse ()
at Proxy.check (admin.js?ver=1751004214:1:170363)
at async admin.js?ver=1751004214:1:374332
X @ vendors.js?ver=1751004214:2

Still persists and the inner content does not load. Only the outer shell with the category tabs.

Could you try again? :slight_smile:

HI Daniele,

The backend loads and the issue is resolved! :grin:
