2.4.0 causes errors

    6 years, 6 months ago

    After updating to 2.4.0, I go to my dashboard and everything starts flickering. It’s hard to get anything to work because the pages keep refreshing. I also get this error message:

    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘autoptimize_flush_pagecache’ not found or invalid function name in /home/[redacted]/public_html/main/wp-includes/class-wp-hook.php on line 284

    When I first saw this this afternoon, I was finally able to turn on Rollback and go back to 2.3.4. Then Jetpack automatically updated the plugin again, but everything seemed to be working okay now, so I left it.

    Hours later, I opened my dashboard again, and the flickering was happening again. Once again I managed to roll it back to 2.3.4, turned off Jetpack’s automatic update, and now it’s fine.

    I am using this snippet:

    // Automatically clear Autoptimize cache if it goes beyond 2GB
    if (class_exists(‘autoptimizeCache’)) {
    $myMaxSize = 10000; # You may change this value to lower like 500000 for 500MB if you have limited server space
    $statArr=autoptimizeCache::stats();
    $cacheSize=round($statArr[1]/1024);

    if ($cacheSize>$myMaxSize){
    autoptimizeCache::clearall();
    header(“Refresh:0”); # Refresh the page so that autoptimize can create new cache files and it does not break the page after clearall.
    }
    }

    …But I don’t know if this is actually related, because I use the snippet with Autoptimize on two sites, and the other site is running normally.

    it looks like *something* (another plugin?) is calling autoptimize_flush_pagecache, which is a function which does not exist any more.

    2 solutions, either;
    * try to find the plugin that does that and disable/ change it
    * or try the following snippet (which re-declares autoptimize_flush_pagecache as a wrapper for the newer equivalent);

    function autoptimize_flush_pagecache() {
    autoptimizeCache::flushPageCache();
}

    the fact that the page keeps refreshing does indicate your snippet (with the header(“Refresh:0”);) is somehow related (but it’s not the one calling autoptimize_flush_pagecache).

    hope this helps,

    When I first installed the new snippet, it spit out this:

    PHP Fatal error: Uncaught Error: Call to undefined method autoptimizeCache::flushPageCache() in /home/[redacted]/public_html/main/wp-content/plugins/code-snippets/php/snippet-ops.php(353) : eval()’d code:4

    Yet so far, the site is working normally, with no more error messages. I’ll keep an eye on it and see how things go.

    No more php errors, but the flickering is back. Also, the snippet to clear the cache no longer appears to be working. I turned off the snippet, which got the flickering to stop, but that means my cache will start filling up fast and have to be cleared manually.

    which confirms the snippet is causing the refresh.

    -> simple solution (while keeping the snippet) would be to comment out the header(“Refresh:0”); line.

    -> better solution would be to configure AO to not fill up cache that fast (the “aggregate inline” options first and foremost).

    -> the in-between solution would be to check if the snippet needs updating (I think the size stuff might be wrong).

    The aggregate inline JS setting makes it fill up, but I have it turned on because of the dramatic improvement in my page speed and scores. I would hate to have to turn it off.

    I commented out the line; I’ll see how it works now.

    I found a plugin to clear the cache: https://www.ads-software.com/plugins/cache-cleaner/ I’ll see if replacing the snippet with this, fixes the problem.

    closing here as the problem is not with AO but rather something hooking into AO, but hope cache-cleaner works for you ??

    have a nice day!
