Hello,
with Theme X in Version 7.2.0 it is possible to update the plugin “Modern Event Calender” to version 5.1.6. There is a security problem with this and lower versions (https://www.wordfence.com/blog/2020/02/site-takeover-campaign-exploits-multiple-zero-day-vulnerabilities/). A fix was provided with version 5.1.7 and there is also a new version 5.1.8. I am not able to update the plugin to version 5.1.7 or 5.1.8. In the wordpress backend a message is displayed:
Beim Aktualisieren von Moderner Event Kalender ist ein Fehler aufgetreten: Aktualisierungs-Paket nicht verfügbar.
In english:
An error has to be changed when updating the modern event calendar: Update package not available.
Can you provide the fixed version for security reasons?
Best regards
Heiko
