Hi there,
Thanks for taking the time to report this problem!
We’ve indeed seen an issue on local by Flywheel, but have not been able to replicate it in any of the other hosting environments we’ve tested.
Could you let us know which hosting provider and plan this was on so that we can investigate?
PHP/WP version would be helpful as well.
This was an issue with Local by Flywheel, where a perfectly valid PHP syntax was causing an NGINX error for some mysterious reason. It’s been solved in the newest plugin version 2.4.2.
