Installation fails -> error output in post

[lecrackffm]

Hello,

since yesterday i am not able to make any new PW installs.

The Installer stops where it should delete unused files etc..

MAMP with PHP 7.1.12

I switched on Test Mode:

warning: Cannot modify header information - headers already sent by (output started at /Users/**/**/**/**/wire/modules/AdminTheme/AdminThemeUikit/install-head.inc:8) in /Users/**/**/**/**/index.php on line 41

Can anyone help?

Thanks

EDIT: using wireshell i am able to make fresh installs.

I switched to ampps and now its working.

But im still interested why installation fails with MAMP

Thanks
