  • Resolved ChrisL


    Iā€™m getting this error when creating posts by email using POSTIE PLUGIN:

    [17-Nov-2018 10:43:24 UTC] PHP Fatal error: Call to undefined function add_settings_error() in /home/username/public_html/wp-content/plugins/wp-fastest-cache/wpFastestCache.php on line 286

    The cache had been cleared prior to creating the post.

    are you talking about the following plugin?



    Yes. That’s the one.



    I have same problem, but I do not know which plugin…

    When I try login to dashboard, then I get fatal error 500 and these logs:

    I fixed the problem. Please delete wp fastest cache and download again to get the latest changes because I did not release a new version.



    Thanks Emre. That did the trick.

    Had the same problem – seems to be VERY common. The fix suggested worked.
