How to resolve warnings when executing wordpress's xmlrpc.xml?

I installed Wordpress on unix hosting provider and now I see warnings when executing xmlrpc.xml?

This is where I see warnin开发者_如何学运维gs

Greatly appreciate in advance for helping me to resolve this problem.

Warnings are just that: warnings. They tell you that something might be broken but it's not enough to cause the script to fail.

The real problem is the fatal error: Fatal error: Class 'IXR_Server' not found

This indicates that WordPress is not installed correctly.

Also, you shouldn't show error messages on production sites. Use error logging instead. This guide should get you started.
