Hello,
Please check to see if you are experiencing a theme or plugin conflict: https://time.ly/document/troubleshooting/first-troubleshooting-step/
The text should show up in all pages, so its most likely a theme conflict somewhere. That said:
If you’re wanting to remove all the extra info from the hover section, you could always do the following:
1. Create a child calendar theme. See https://time.ly/document/customize-calendar/create-new-calendar-theme/ for details.
2. Copy …../all-in-one-event-calendar/public/themes-ai1ec/vortex/twig/event-popup.twig to the twig folder in your child calendar theme. If you don’t have a twig folder, create one.
3. Edit the copy of event-popup.twig in your child calendar theme to remove the sections you don’t want. Twig is a template engine, and you can see documentation at http://twig.sensiolabs.org/documentation (specifically look at Twig for Template Designers).
4. Only once you’ve edited this, change your calendar theme in Dashboard->Events->Calendar Theme to your child calendar theme. If you want to edit further, make sure to change back to another calendar theme (Vortex is the default). Only edit the theme when it’s inactive, as otherwise you might get issues with caching.
Note: If necessary, you might need to disable caching, or clear the ai1ec cache. If you disable caching the site will be slow, so remember to enable it again once it’s the way you want it.
If you do not want ANY hover section for events, do the above and edit event-popup.twig so that it’s an empty file (do not delete). This will override the default one so that nothing gets shown.
The template system will fall back to the default files if you don’t define a new template. In this way, you don’t need to create a complete calendar theme from scratch, but just edit/blank the files you want to achieve the desired behaviour.
