    Hello madam or sir,

    All of a sudden, my WP-Optimize is causing (seems to cause) PHP errors. Please see below an error from my log file. There are 1000 of these lines in my error log.

    Uncaught Error: Call to undefined function WP_Optimize() in /home/u51255p58880/domains/XXXXX.COM/public_html/wp-content/plugins/wp-optimize/cache/file-based-page-cache-functions.php:178\nStack trace:\n#0 [internal function]: wpo_cache('<!DOCTYPE html>...', 9)\n#1 /home/u51255p58880/domains/XXXXX.COM/public_html/wp-includes/functions.php(4757): ob_end_flush()\n#2 /home/u51255p58880/domains/XXXXX.COM/public_html/wp-includes/class-wp-hook.php(292): wp_ob_end_flush_all('')\n#3 /home/u51255p58880/domains/XXXXX.COM/public_html/wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters(NULL, Array)\n#4 /home/u51255p58880/domains/XXXXX.COM/public_html/wp-includes/plugin.php(484): WP_Hook->do_action(Array)\n#5 /home/u51255p58880/domains/XXXXX.COM/public_html/wp-includes/load.php(1072): do_action('shutdown')\n#6 [internal function]: shutdown_action_hook()\n#7 {main}\n thrown in /home/u51255p58880/domains/XXXXX.COM/public_html/wp-content/plugins/wp-optimize/cache/file-based-page-cache-functions.php on line 178\n, referer: https://www.XXXXX.COM/

    Only after completely removing the plugin, the errors stopped. So, only disabling the plugin did not help. Can you please advise what is causing this errors?

    Thanks in advance!

    Denny

  • @denny_p `It looks like some core WP-Optimize files are missing.

    Can you please upload the plugin via FTP/SFTP instead?

    To do this:

    1. Unzip the WP-Optimize ZIP on your local machine, using a zip utility such as 7-zip.
    2. Access your WordPress installation via FTP or your host’s filemanager.
    3. Navigate to wp-content/plugins. Upload the WP-Optimize folder here.
    4. Go to the Plugins page on your WordPress dashboard. You should see WP-Optimize in the list of plugins.

    Let us know if above steps helps to fix the issue?

    Hello Harshad,

    I hoped this was the issue (as the site was just moved by hoster from VPS to dedicated server), but unfortunately, after uploading via FTP and activating the plugin, I got the same errors again:

    Any other ideas maybe? Thanks in advance!
    Best,

    @denny_p Do you have any other cache plugin installed, or have cache mechanism on your server? If yes, could you please temporarily disable it and check if you still get the errors?
