Support » Plugins » [Plugin: WP Super Cache] supercache breaking xml-rpc somehow

  • I upgraded to 0.9.3 yesterday and one of the XML-RPC calls began failing. I’m posting via XML-RPC. The actual post call works, but the “publish” call results in an error. Digging into the Python XML-RPC library, here’s what I found the server was returning:

    <br />
    <b>Warning</b>:  opendir(/home/nickarne/public_html/tweetsnet/wp-content/cache/meta/) [<a href='function.opendir'>function.opendir</a>]: failed to open dir: No such file or directory in <b>/home/nickarne/public_html/tweetsnet/wp-content/plugins/wp-super-cache/wp-cache-phase2.php</b> on line <b>632</b><br />
    <br />

    Changing supercache to “half-on” seems to have solved the problem.

    It appears to me that the Python library was unable to parse that error message… it throws “ParseError: junk after document element: line 2, column 0”. I’m not sure what’s going on here… is supercache not playing well with XML-RPC?

  • You should turn off “Display errors in your php.ini and download this file and copy into your plugins/wp-super-cache/ folder. It will overwrite the one already there.

    Thanks! Took me a few minutes to figure out that the first thing is not a WordPress setting, but I’ve got that done.

    I’m just curious about the second step. Is that essentially to restore that file to its original?
