Hi there,
Thanks for following up. I have contacted Fasthosts with the information that this forum provided i.e.
often points to a server-side resource limit (usually PHP memory or a 503-level error) getting hit during block registration rather than a plugin conflict, which is why deactivating Jetpack entirely restores editing. Fasthosts’ hosting environment may need a memory limit adjustment to handle Jetpack’s block registration properly.
✅ Check server error logs for the specific memory or 503 trigger
✅ Test PHP memory limit increases through Fasthosts hosting settings
I am awaiting feedback, so pleasae keep this open
VMT
Phil
