Hi there,
I am wanting to upgrading to Joomla 4 from Joomla 3 for this website: http://bellhowleyperrotton.co.uk/ (still in dev).
When I go to do the update this shows: https://bellhowleyperrotton.co.uk/Screenshot.png.
I've goen ahead and done the update and it breaks the whole site (I have uploaded my backup).
What do I need to do in order to be able to upgrade to Joomla 4, thanks,

Hi,
- About SPPB plugins warnings - you can still upgrade, it's OK. Trust me.
- Helix3 template - this template is not yet ready for Joomla 4.0.x - you have to wait for offcial update (next weeks), or switch template to different one. You can disable all helix3 plugins for migration period.
- Heix Ultimate - is Joomla 4.x ready, if you have the last version installed (2.0.5/6). Update plugin.
- SP Cookie Consent - please disable plugin for migration period, then upgrade plugin to J4 version after.
In general, I recommend wait with Joomla 4 upgrade few weeks. Not only here, we meet people who have many problems with new J4.0.4, core still buggy in many ways. Of course you can do as you like.
