    Hello,

    I get the following error message.

    The time is correct when the cache is regenerated.

    Hello,

    Thank you for reporting this. Please could you deactivate and uninstall WP-Optimize and then reinstall and reactivate it. The fatal error is thrown by the WordPress core and not WP-Optimize. If the issue persists you may need to update the WordPress core files.

    Hello,

    thanks for the answer I will try it.
    I updated WordPress to the latest version 6.4.2 yesterday. That shouldn’t be the problem, right?

    Hello,

    You’re welcome, it may indeed be due to an issue with the upgrade and so it may be necessary to overwrite the core files with new ones. Some of them may not have been updated correctly.

    I deactivated the plugin and reinstalled it. Unfortunately, the error occurred again a few times.
    I have now reinstalled the WordPress core files and will now monitor it…….

    Did you have more than one caching plugin installed on your site? (this is the normal cause of the issue)

    I only use Autoptimize, but this combination has worked without any problems so far.

    Also copying the WordPress core files did not help. The error occurred several times again.

    Please could you check with your host to see if external object caching is used?

    (@jidwictut9)

    Hello, no external caching is active. Only browser caching via the .htaccess.

    I am temporarily using a different cache plugin and no longer get any error messages. So it is definitely due to WPOptimze.
    Since I would like to continue using your plugin, it would be great if you could fix this error.

    This appears to be quite a well documented error with Auto optimize.

    Have you tried disabling your minification for CSS?

    Is auto optimize the only other caching plugin you are currently using (you said you are using another temporarily). If so can you also deactivate his when you test WPO with the CSS minification?

    Hello,
    I am currently using Autoptimize in combination with Cache Enabler. WPOtimize is deactivated because of the error.
    So far I have not tried to disable the compression of Autoptimize, because I am very happy with it. But I will test and observe it in the next few days.

    I have just carried out a few tests. With the compression of WPO, the values for mobile are much worse (image 1) than with Autoptimize/Cache Enabler (image 2).

    This appears to be quite a well documented error with Auto optimize.

    Never seen AO cause wp_cache_get to fail before, but always interested in learning about that one @vupdraft ??

    So far, the error has not occurred again. But the performance of the page is worse with WPO as with WPO/Autoptimize and Autoptimze/Cache Enabler. The combination WPO/Autoptimize has worked best so far.

    Do you have a plugin that adds Object cache, or is there a file called?object-cache.php?in your website’s?wp-content?folder?

    Here are some articles regarding wp_cache_get in case they are helpful.
