    Hi,

    I caught a PHP Notice in version 0.15.1. Can you fix this in the next version release? Thanks for this awesome plugin!

    Notice: Undefined index: path in /wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php on line 1470

    Hello @erikmolenaar

    I am sorry about the issue you are experiencing and I am happy to assist you with this.
    That is supposed to be populated before that line. It’s most likely a request with no available request URL.
    It may have to do with flushing page cache at /wp-content/plugins/w3-total-cache/PgCache_Flush.php on line 311
    Can you please share if the notice is logged consistently or if it appears only once in a while?
    Thanks!

    Hi Marko,

    Thanks for your prompt reply.

    I am getting it approx. every 20 minutes on a website with about 30k sessions p/month.

    So my guess is there is a scenario where this line is not populated, could be a no available request URL indeed.

    Hello @erikmolenaar

    Thank you for the information. Does it happen after a post is being updated or a new article published? Anything that could lead to flushing of a single URL cache entries?
    Thanks!

    Hi Marko,

    Thanks again for your prompt reply.

    I am sorry but I am not sure. From the looks of the Referer URL containing gclid this error was produced when a site visitor came from a Google Ads link. But I can’t tell why the /?wc-ajax=get_refreshed_fragments parameter was there nor when this (or any other) post was updated or published.
