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
It looks like all the messages are surrounding phpMyAdmin's libraries directory, does that directory exist? If so, what are the permissions?
I see this error here which seems to be directly related to apc.:
Notice: require_once() [function.require-once]: apc_cache_make_file_entry: entry->data.file.filename is [C:\wamp\apps\phpmyadmin3.3.9\libraries\common.inc.php] in C:\wamp\apps\phpmyadmin3.3.9\index.php on line 35
Also, these aren't errors, but notices, does myadmin function despite these?
Finally, I found this blog post, does this help? It seems like you can disable APC for phpmyadmin.
