Hi Irina!
Just wanted to share with you that a new release of our plugins is out, including a fix for this issue 🙂
Find out more about this release → https://theeventscalendar.com/maintenance-release-for-the-week-of-9-september-2018/
We apologize for the delay and appreciate your patience while we worked on this.
As always, we suggest to setup a dev/staging site so you can make all plugin updates without disrupting the live site.
Please update the plugins and see if the fix works for you. As always, don’t hesitate to open a new topic if anything comes up.
Best,
Victor
