Fatal error with bricks and 1.9.0

Max Elman

I don't have time to troubleshoot this right now, but my client (Editor) user got a fatal error when trying to access the page editor. Deactivating CommandUI and the problem is resolved. Error info:

Hey Max,

What other plugins do you have? This sounds like some three-way interaction.

I suspekt that it would work with just Bricks and CommandUI. Are you able to Test that?

Max Elman

Not a plugin, tried without any others. I tracked it down to this setting on Bricks: https://rzfg.co/i/zYWUQ3

If Editor is set to Edit content or No access, loading the page with CommandUI breaks. To clarify - that's loading the page in the Bricks page builder, or the default WP editor (Bricks allows both).

If Editor is set to Full access, loading the page with CommandUI works fine.

So something in these settings is conflicting with CommandUI: https://academy.bricksbuilder.io/article/builder-access/

Unfortunately I need to limit Editor editing access, so I'll need to deactivate CommandUI for now. Or maybe I can disable it for Editors?

Thanks Max, that's very helpful. I'll be able to debug this with this info and ship a fix in the next release.

For now, you can limit CommandUI to admins only.

Max Elman

Confirmed on a second site as well - same setup. Happy to send you staging site info if that's helpful.

This snippet/Hook can be used to unload CommandUI dynamically:

(Ask AI to make it for admin only based on the snippet there)
