After updating to 8.6, everything looked great, until I started opening existing websites.
My Bootstrap customise theme fonts and font colours are not working. Tried resetting them, and nothing changes on the site. I am a little stuck now 
I have reported it to support, just posting so others are aware.
Update:
I had to downgrade to the previous version of Pinegrow to get my websites back. I did get a popup that something related to node.js being a too newer version or something.
FYI to everyone. I have the exact same issue with the Windows Version.
@PeteSharp @Cruachan we are looking at the issue. Are your projects using Page ā Customize Bootstrap Theme in combination with the Design panel? Or just the plain Bootstrap Design panel?
This may sound silly, but how do I tell?
If you can explain how to check I will be able to reply.
Thanks
All missing for me 
@PeteSharp @Cruachan the font issue in the Design panel should be fixed now. We pushed a patch through the server so you just need to restart the Pinegrow 8.6 (not needed to reinstall it). Please try and let me know if it works ok now.
Thanks!
Yes, the option is active for me.
I will retry tomorrow morning Australian East Coast time and let you know the outcome..
Thanks
Similar issue here with Design Panel, Windows 11. Not using the āCustomise Themeā Sites previously created using BS 5.3 and design panel are not displaying correctly inside pinegrow but looks ok in browser. displaying very strangely within pinegrow. Never had this issue before.
Wow. Thank you @matjaz, loaded a couple of different sites and they are back!!!
And the site yesterday I needed to push for a client review, I had quickly modified with a custom class, I was able to revert that back, with the handy dandy Find & Replace tool 
to strip the class out.
Unfortunately the issue still remains for me. I have sent some screen shots to support and hopefully those will be of some use
Whatās happening is Pinegrow is erasing everything in the boostrap.css file under the folder ābootstrap_themeā. If I reload it via VS Code everything comes back and the site looks correct again. But of course as soon as you restart Pinegrow, the file gets empitied again and youāre back at square one. My quick workaround was to deactivate the design panel, now everything is back to normal. But of course that means I canāt use the design panel.
I have spoken to soon. Just loaded an older project from earlier this year, and itās still broken. So it seems the patch is not working in every case here @matjaz
The latest update 8.61 has resolved my issues and everything is back to normal
Nice.
8.61 is working now on my older projects too. Excellent.
Thanks @matjaz for the quick turn around to solve this.
Thank you all for your help in troubleshooting the issues!
