Hi @NoemieSEGUY - no worries! Here is a link to another thread with the solution - PHP v7.3.5 ONLY usable on Mac 10.13.6 (High Sierra) - #2 by austinwendt
Here’s the steps to take:
- Close Local
- Hit Cmd+Space and type
~/Library/Application Support/Local/lightning-services
to navigate to this folder on your computer - Delete the entire
lightning-services
folder - Re-open Local
- Create a new site with the PHP/database versions you were trying to use.
This will fix the issue for all of your existing sites the next time you start them. We’re working on a fix for the issue!
