  4. Go to the calendar page, click on a free date and start with your first calendar entry in the popup menu.
    Thats it, all else is detail configuration:
  5. Check if your WordPress template is ok with the calendar. You find a list with information in the admin menu
  6. Check if you have a caching plug-in or method active. Just try to move a item on the calendar. If after refresh it stays at the new place (Remark: recurring events can not be moved) all seems fine. If after the automatic page refresh the item jumps back, you need to switch off caching for this page. More Info in Help.

  8. That’s it, hope you will enjoy to work with the easy Termin-Kalender calendar.

Nejčastější dotazy

If i upgrade to PRO, do i need both versions installed?

No, before installing the PRO version, please deactivate (later uninstall) the free version. You dont need both, your free calendar data will not be lost.

Where can i find Help and detailed Information about the Termin-Kalender

Visit our Website: termin-kalender.beatkueffer.ch

What can i do, if something does not work

Actually this is the first public release of the easy frontend calendar called Termin-Kalender. Please download and try the free version first, before you buy PRO with all his possibilities. If your PRO license expires, no data is lost and you can continue using the calendar but some settings features and backup will not be available in the free version.

My calendar shows too small

Change the calendar page to use a wide template (full page width). Depending on the wordpress themes you are using, try to remove header, footer and sidebars.

My calendar does not show changes

If your changes does not show after saving, you most probably have a CACHING Plug-In active and you need to EXCLUDE the my-easy-kalender page from caching. Try to switch off your caching plugin and LET US KNOW if there is a difference, so we can try to improve the Termin-Kalender. Please EXCLUDE the calendar page in your caching plugin options.

Late Beta works well so far. Before installing PRO, uninstall FREE and EXCLUDE the calendar page in caching settings, if you use a caching Plug-In and new calendar entries or changes does not show immediately.
