Support » Plugin: Cache Enabler - WordPress Cache » Fatal Error in index.html

  • Resolved delaspuke


    Hello, there,

    in the Google Search Console I get a message that the index.html is an error.

    The following is in the index.html

    Fatal error: Uncaught Error: Call to undefined function wp_die() in /www/htdocs/XXXXXXX/neu/wordpress/wp-content/advanced-cache.php:158 Stack trace: #0 /www/htdocs/XXXXXXX/neu/wordpress/wp-content/advanced-cache.php(9): _ce_file_path() #1 /www/htdocs/XXXXXXX/neu/wordpress/wp-settings.php(84): include(‘/www/htdocs/XXX…’) #2 /www/htdocs/XXXXXXX/neu/wordpress/wp-config.php(64): require_once(‘/www/htdocs/XXX…’) #3 /www/htdocs/XXXXXXX/neu/wordpress/wp-load.php(37): require_once(‘/www/htdocs/XXX…’) #4 /www/htdocs/XXXXXXX/neu/wordpress/wp-blog-header.php(13): require_once(‘/www/htdocs/XXX…’) #5 /www/htdocs/XXXXXXX/neu/wordpress/index.php(17): require(‘/www/htdocs/XXX…’) #6 {main} thrown in /www/htdocs/XXXXXXX/neu/wordpress/wp-content/advanced-cache.php on line 158

    What could be the problem here?

    Thank you for your help.

  • How long have you had Cache Enabler active on your site? Did you recently make any major changes to your site? Also what version of CE are you running?

    I’ve been using Cache Enabler for several years. Currently in version 1.3.1.

    A few weeks ago I activated the function WebP Format for Optimus.

    Hmm that shouldn’t cause any index.html issues. Have you tried deleting and re-installing the plugin? Also, is your site delivered via HTTP or HTTPS?

    I deleted the plugin and reinstalled it. Error remains.

    The website works with https.

    I have the same problem. Any news on it or any solution available?

    I only realized the problem as Google Search Console gave a warning for “index.html” in the section Mobility Usability as the error page is not mobile friendly.

    (following) I have a site with this problem as well.

    Can anyone experiencing this issue please provide their site URL as well as a screenshot of the error in Google Search Console?

    Here is my site URL:

    If you add index.html you will find the error.

    My Search Console is in German so a screenshot won’t be very helpful, but that was only the reason I discovered the error. The error just states that the page index.html is not mobile friendly. Which is true. No viewport set and text too small.

    The problem however is not Google Search Console reporting the error, the problem is that there IS an index.html in the first place.

    Hope to have made myself clear here 😉

    This has been fixed in version 1.3.3. Please upgrade to the latest version.



    Thanx, it seems to work.

    I have now redirected my index.html to index.php so you can’t check it anymore 😉
