<\/span>MEC Not Working: Quick Troubleshooting Checks<\/span><\/h2>\n\n\n\n

Before troubleshooting a specific problem, perform the following basic checks.<\/p>\n\n\n\n

<\/span>Clear Your Cache<\/span><\/h3>\n\n\n\n

After installing or updating MEC or one of its add-ons, cached files can sometimes prevent the latest version from loading correctly.<\/p>\n\n\n\n

    \n
  1. Clear the cache of your WordPress caching plugin.<\/li>\n\n\n\n
  2. If you use a CDN such as Cloudflare, purge the CDN cache as well.<\/li>\n\n\n\n
  3. Hard-refresh your browser using Ctrl + Shift + R<\/code> on Windows or Cmd + Shift + R<\/code> on Mac.<\/li>\n<\/ol>\n\n\n\n

    If the problem started immediately after an update, clearing all caches should be one of the first things you try.<\/p>\n\n\n\n

    <\/span>Check Your WordPress and Server Requirements<\/span><\/h3>\n\n\n\n

    Go to: WordPress Dashboard > Tools > Site Health > Info<\/strong><\/p>\n\n\n\n

    Check the WordPress<\/strong> and Server<\/strong> sections.<\/p>\n\n\n\n

    Make sure WordPress is up to date and that your PHP version meets MEC requirements. MEC requires PHP 5.6 or later, although PHP 7.4 or newer is recommended.<\/p>\n\n\n\n

    <\/span>MEC Cannot Be Installed<\/span><\/h3>\n\n\n\n

    If WordPress shows an error such as:<\/p>\n\n\n\n

    \n

    The link you followed has expired. Please try again.<\/p>\n<\/blockquote>\n\n\n\n

    the problem is often the maximum upload size configured by your hosting provider.<\/p>\n\n\n\n

    To check the current limit, go to:<\/p>\n\n\n\n

    Tools > Site Health > Info > Media Handling > Max upload file size<\/strong><\/p>\n\n\n\n

    <\/span>

    Read Also: <\/p>Site Health: keep your website healthy<\/a><\/span><\/div>\n\n\n\n

    If the limit is too low, ask your hosting provider to increase it. A value of 64 MB is generally sufficient for MEC.<\/p>\n\n\n\n

    As an alternative<\/strong>, you can extract the MEC ZIP file and upload the plugin folder directly to:<\/p>\n\n\n\n

    wp-content\/plugins<\/code><\/pre>\n\n\n\n
    Then activate MEC from: Plugins > Installed Plugins<\/strong><\/p>\n\n\n\n
    <\/span>Update MEC and Its Add-ons<\/span><\/h3>\n\n\n\n
    Compatibility problems can occur when MEC, WordPress, your theme, or MEC add-ons are running different or outdated versions.<\/p>\n\n\n\n
    Go to: MEC > Addons<\/strong><\/p>\n\n\n\n
    Update any add-ons that have an available update. You should also update MEC itself. You can use either the automatic update<\/a> or manual update<\/a> method.<\/p>\n\n\n\n
    After updating, clear your website and browser caches again.<\/p>\n\n\n\n
    <\/span>Quick Checks<\/span><\/h2>\n\n\n\n
    <\/span>Re-save MEC Settings<\/span><\/h3>\n\n\n\n
    Go to: MEC > Settings<\/strong><\/p>\n\n\n\n
    Without changing any options, click Save Changes<\/strong>.<\/p>\n\n\n\n
    This can refresh MEC’s configuration and generated style files and is a safe first step when an existing configuration starts behaving unexpectedly.<\/p>\n\n\n\n
    <\/span>Test With a New Shortcode<\/span><\/h3>\n\n\n\n
    A shortcode can contain many filters and configuration options. Creating a new basic shortcode can help determine whether the problem is caused by MEC itself or by the configuration of the original shortcode.<\/p>\n\n\n\n
    Go to: MEC > Shortcodes<\/strong><\/p>\n\n\n\n
    Create a new shortcode and leave its options at their default values.<\/p>\n\n\n\n
    Copy the generated shortcode, for example:<\/p>\n\n\n\n
    [mec id=\"123\"]<\/code><\/pre>\n\n\n\n
    Create a new WordPress page, insert the shortcode using a Shortcode block\/widget<\/strong>, and check the result.<\/p>\n\n\n\n
    If the new calendar works, the problem is probably related to the settings of your original shortcode. Compare the two shortcodes and check their filters, date ranges, categories, and other options.<\/p>\n\n\n\n
    <\/span>

    If the new shortcode does not work either, continue with the troubleshooting steps below.<\/p>\n\n\n\n
    \n
    Make sure the quotation marks in your shortcode are standard quotation marks (\"<\/code>). Smart quotes copied from emails, documents, or forums may prevent WordPress from correctly processing the shortcode.<\/p>\n<\/blockquote>\n\n\n\n
    <\/span>The Calendar Is Not Showing<\/span><\/h2>\n\n\n\n
    If the page does not display the calendar, or you can see the shortcode itself instead, check the following.<\/p>\n\n\n\n
