Problem 1
- Root composer.json requires roots/wordpress dev-main -> satisfiable by roots/wordpress[dev-main].
- roots/wordpress dev-main requires roots/wordpress-no-content dev-main -> found roots/wordpress-no-content[dev-main] but it does not match your minimum-stability.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
