Database connection information did not work.

Hey there,

I have a big problem with an Processwire installation on a 1und1 server.

I made the whole site locally. Now I switched to the liveserver and nothing works. The following debug message I became:

And yes, I use the newest version of processwire.

Fatal error: Exception: SQLSTATE[HY000] [2054] Connecting to 3.22, 3.23 & 4.0 servers is not supported (in /homepages/1/d11728757/htdocs/website/wire/core/ProcessWire.php line 143) #0 /homepages/1/d11728757/htdocs/website/wire/core/ProcessWire.php(51): ProcessWire->load(Object(Config)) #1 /homepages/1/d11728757/htdocs/website/index.php(185): ProcessWire->__construct(Object(Config)) #2 {main} in /homepages/1/d11728757/htdocs/website/index.php on line 216

So I tried out a clean installation. At the installation process I get this error:

Database connection information did not work.
SQLSTATE[HY000] [2054] Connecting to 3.22, 3.23 & 4.0 servers is not supported

Any ideas how can I fix this problem?

Best, Kai

Hi, this error message looks to me like old mysql on server. Can you tell us which versions of PHP and mysql are on server?
