I use macOS Sierra 10.12.3 and Ampps 3.6. I've set php version to 7.0 in ampps control panel, restart apache and everything is working properly. But when I quit Ampps (Cmd + q) and then start it again I get an error "Error displaying the error page: Application Instantiation Error: The MySQL adapter mysqli is not available". Ampps control panel shows that Apache is ON, MySQL is ON, PHP version is set to 7.0. If I add/remove any php extension and restart apache, everything is fine again. Question is why ampps doesn't start php in right way after relaunch. Any ideas?

Ampps error mysqli adapter is not available after Ampps relaunch
Figured this out. So... When I relaunch ampps, it deletes php.ini file in /Applications/Ampps/php/etc and doesn't create a new one. So until you not turn on/off any of php extensions and restart apache, there will be no php.ini file in etc folder.
Please, fix it.
