About the timezone issue from Ashan:
Thank you for letting us know. Event though it shows as london the value is saved in settings. Just the correct saved value is not showing. We will correct this in the next version update. In the mean time here is the patch fix to resolve this issue.

Hello,
On my side:

Have you managed to fix the issue?
4.8.2 version of EventON has an issue with EventON > EventCard > Feature image display style: Scaled cropped image to fit the full box.
I changed it, so the image is visible now.
I disabled WP_DEBUG on your website. Do you notice any difference?
debug.log file isn’t creating for some reason.
However, after I changed the calendar started working:


So I believe that the issue is related to memory limit:

About WP_DEBUG, could you contact your hosting provider and ask why debug.log file isn’t creating. Maybe there is an issue similar to:

Could you try removing hide_et_tags=”yes” from the shortcode?
Are you still seeing the issue with EventON 4.9.1?
We are sorry for the delay. Ashan will take a look ASAP.
