PHP 7.0 on a Rochen host
Duplicate #18783
Have exactly same issue using PHP 7.2.1 on Apache 2.4.29 server at Strato hosting provider.
User Agent Chrome/64 on Windows 10.
Have exactly the same using PHP 7.0, 7.1 and 7.2 on Apache server at Versio hosting provider.
Reloaded alle files again, same result.
No database type selection possible.
Please use https://github.com/joomla/joomla-cms/archive/4.0-dev.zip to test. Alpha is really too old (And choose mysqli when installing).
Thank you very much for your help!
Thanks for the download, I now only see the possibility for selecting databse MySQL(PDO). No other selctions possible.
Trying to use MySQL (PDO) instead of MySQLi gives error.
Not possible to select MySQLi in field, only option displayed
is MySQL (PDO)
Choosing MySQL (PDO) will not let you proceed (the driver itself is OK but some code has to be modified in core to use it).
It is weird though that you do not see mysqli in dropdown.
Just for yr information I here by enclose the downloaded files of Joomla 4.0 Beta
Downloaded files Joomla 4.0 Beta.pdf
Still a duplicate of https://github.com/joomla/joomla-cms/issues/18660 which is apparently still waiting for me to find a moment in my copious amounts of free time to fix all these months later.
Thanks for yr reply. I will silently and relaxed wait for a solution, because I seem not be able to fix the issue.
This issue occurred on a HostGator shared server. It did not occur on a GoDaddy shared server nor on WampServer. The WampServer was on a PC running Windows 7. I have informed HostGator of the issue and and talked to a tech rep that took an interest in the issue. Both GoDaddy and HostGator are running Apache with a cPanel interface -- but the two interfaces are quite different. JLH 180521
UPDATE: 180521
For shared hosting, I have determined that GoDaddy has MySQLnd support in its PHP Configuration and HostGator does not have MySQLnd support in its PHP Configuration. I don't know if this is the only difference between the two or not.
