Headers and client library minor mismatch!

ogolabernard · October 28, 2010, 7:09am

I get this warning when I do a test on my localhost: “Headers and client library minor version mismatch. Headers:50051 Library:50151”. The warning notwithstanding, the browser is able to successfully establish database connection. Where could i be going wrong? And what are these “headers and library” stuff?

That’s a nice list, Mitt

Most of the time, a connection mismatch is due to different versions of MySQL and the PHP plug-in.

I would suggest to go through the threads Mitt listed because some people found different solutions to the problem.

Some simply installed MySQL latest version and that solved it. Others found that they had to change one line in the Apache’s http.conf file.
