Yes, according to P3 (Plugin Performance Profiler), “All-in-One Event Calendar by Time.ly – 0.3513 sec – 24.97%” … that’s 1/4th of the total page loading time! When I tried to run the ‘Php Compatibility Checker’ on it, the error was, “The plugin/theme was skipped as it was too large to scan before the server killed the process.” Also, the plug-in details in the WordPress dashboard page never loads (blank pop-up page), even though the update feature works when there is a new version. Please improve, thanks!
