Joomla! 3.7.5 has been released to fix a bug introduced in Joomla! 3.7.4 relating to the implementation of additional security checks in the install application designed to protect web hosting account from being overtaken by a remote attacker.
The patch only changes one file in the installation folder so nothing changes for existing installations except the version number.
Bug Fix:
Joomla! is not installing on remote databases
