 * Hi,
 * after configure the Pluging, Theme-Option….
    I take a look at the source code
   of our site, and the “<header>” entry has errors. The Plugin Style in <link rel
   =’stylesheet’ id=’ai1ec_style-css’ href=’//…’ /> has no “HTTP” or “HTTPS” at 
   the beginning of “href=’//…'” tag.
 * Need some help…
 * Best regards
    Mirko

 * Hi [@mtopp](https://wordpress.org/support/users/mtopp/),
 * I suggest a manual reinstall. These instructions will preserve your current events:
 * – Perform a complete back up of your database before proceeding further
    – Delete
   the file uninstall.php from the plugin directory that is currently on the server(
   found under /wp-content/plugins/all-in-one-event-calendar). Deleting this file
   ensures that when you uninstall the current version of the plugin, your event
   data and calendar settings will be preserved when you delete the plugin (don’t
   skip this step – it’s important!) – Deactivate the All-in-One Event Calendar 
   using your WordPress Dashboard. – Delete the All-in-One Event Calendar using 
   your WordPress Dashboard. – Database -> wp_options, click option_name to sort
   and delete everything with ai1ec_, this will delete plugin settings but events
   will remain in the database. – Now install the latest version.

 * Hi [@mtopp](https://wordpress.org/support/users/mtopp/),
 * I noticed there is a problem clicking on the events, the dropdown does not expand.
 * This error is most likely a result of a plugin or theme conflict (usually caused
   by a caching or security plugin)..
 * To fix this, 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 @suny454,
 * last night i switch the theme to twenty seventeen, disable all other pugins.
   
   remove the all in one calendar plugin as described above.
 * Same as before. No [https://&#8230](https://&#8230);.

 * Besides the https issue.
 * When you disable the other plugins and change the theme, does the calendar work?
   Right now, nothing works, the buttons are not clickable (clicking does nothing).
 * There should be no issues with https, because the calendar loads fully secure.
   See the screenshot of the calendar in Google Chrome:

 * [@mtopp](https://wordpress.org/support/users/mtopp/),
 * There is no issue with https on your website. The screenshot you sent shows that
   the link is correct.
 * I asked you to disable all other plugins in order to check for a conflict that
   is causing a different problem on your website as I explained in my previous 
   message.

 * No issue?
    I already told you that it has no effect to disable all other Plugins.
   Caledar doesnt work.
 * If i manualy correct the Brocken Link in Header, it works.
 * Sorry, But i will Use an other event plugin.

 * Please re-read my last message. YOu are mistaken. Once again, your calendar does
   not have any problem with https.
 * I was addressing another problem with your calendar and provided you with steps
   to trouble shoot a possible conflict. You do not have to do those steps. I already
   explained all this but it doesn’t seem you are reading my messages.
