Sadly i get an error when installing your app on my webspace. I already had contact with the hosters support team. They can not deal with the message, and told me, that there is nothing they can do.
Permission set "777" for complete folder. Hoster is "bplaced.net", i do not have direct acess to apache server.
Specific part fron Eror log:
production.ERROR: is_executable() [<a href='http://de.php.net/function.is-executable'>function.is-executable</a>]: open_basedir restriction in effect. File(/usr/share/7.2/pro/bin/php) is not within the allowed path(s): (/users/famepple/:/users/_temp/famepple)
Please, take a look at it.
