I have installed \'WampServer2.1e-x32\' stack with addon version of php 5.2.11 . I downloaded apc3.0.19.dll and placed under the directory and required information in php.in
I don't think these errors are actually problems with PHPMyAdmin; they're part of the APC configuration settings. Apparently debugging was enabled. I think this can be resolved via https://stackoverflow.com/a/9032478/263877.
