  • Hi @rztab,

    Be sure that your WordPress installation and all our core calendar plugin is up-to-date, and if not update them under Plugins.

    If the error still occurs, if your host is running PHP version 7+ you can try having your host revert back to PHP versin 5.6 which is apparently more stable and causes a lot fewer problems.

    Hi @sunny454, a single site installation with the same PHP version makes no problems. The problem occurs in a multi-site installation.
    And all plugins are uptodate

    @rztab:

    Thanks for the info. There was a bug with multi-site installations but it was fixed a few releases ago. This problem could be a result of a plugin or theme conflict (usually caused by a caching or security plugin).. Please try a different theme temporarily such as Twenty Seventeen, or, disable all plugins and then check if the problem recurrs — then re-enable each one until you find which one caused the problem. Let me know the results.

    Hi,

    I’m having this same error when I switch to PHP5.6 from PHP7.

    The site loads OK at PHP7 but I can’t get into wp-admin as it throws a 500 error. Switching back to PHP5.6 gets it working again.

    I’ve don’t have any caching or security plugins running. Deactivating all plugins still causes wp-admin to 500 error. Is there any reason why the latest version (2.5.26) doesn’t fix this?

    Hi @sallymoos,

    Unfortunately, I don’t know why this fixes the problem. This is a arbitrary compatibility issue that PHP 7+ has had on some websites. But there is no specific information as to why this latest version (7+) breaks operation of some functions or spits errors. In your case, it looks like it is breaking your WordPress dashboard administration. Suffice it to say that it is unstable.
