I was having the same issue and then I disabled GZIP Compression under Settings > Advanced Settings and enabling Frontend Rendering as well.
Hope this helps.
Thank you, I have tried this but the issue is still same.
Hello @muhammad-abbas,
This error could be a result of a combination of factors that can cause a conflict:
– your server’s PHP version
– your version of our Calendar
– other plugins you have installed
To fix:
Go to your WordPress Dashboard, then to Plugins > Installed Plugins. Disable all plugins and see if the error goes away. If so, activate one at a time until you find what’s breaking things.
