Your calendar theme has been switched to Vortex due to a rendering problem.

Hi,

Please check your php memory limit, install this plugin and post back with what it reports: https://www.ads-software.com/plugins/wp-memory-usage/

Hi,

It says, Memory : 82.51 of 128

Please edit wp-config.php file (in the WordPress root folder) and modify line:
define('WP_DEBUG', false);
to
define('WP_DEBUG', true);

Then please navigate to your calendar page or site. It should produce useful trace information.

Thank you for your prompt replies, I did a manual uninstall following this link: https://time.ly/document/user-guide/troubleshooting/perform-manual-upgrade/

I removed the current version and downgraded to an older version (2.2.0). The calendar is working again, but the extended views plugin deactivated, I tried to install an updated version following this link: https://time.ly/wordpress-calendar-plugin/addons/extended-views-2/

But it won’t activate, I get a message “Are you sure you want to do this? Please try again.”

Please try to upload files via FTP and then activate the plugin.

I tried via FTP, still same error.

It is necessary to upgrade the core and extended views plugins, otherwise addon will probably not work.
