Cannot regenerate event table / error 500 / Undefined property

Hi Joe,

We added a new multi-day event today, and noticed that it showed up completely wrong on the front end — rather than two days in April, it listed its dates as being eight days in September. Very bizarre, so as my first troubleshooting step, I went to regenerate the event occurrences table.

1) “Regenerate event occurrences table” => Save: The page spins for a minute or two, then resolves to an error code 500: Internal Server Error page. This is the only thing on the whole site that yields that error. Since I keep trying to do it, the calendar is now not showing any events, or only a few, but not all of them because it cannot complete.

Deactivated all other plugins, did a fresh install of the calendar plugin, bumped up the WordPress memory limit, tried a different theme. No help.

2) Turned on WP DEBUG and now, when I go to the Manage Events page, I see a looooooong list of PHP errors which all amount to: “Notice: Undefined property: stdClass::$occur_end” and “Notice: Undefined property: stdClass::$occur_id” in the my-calendar-templates.php and my-calendar-core.php files.

I don’t know if #2 is related to #1? But do you have any idea what could be going on with either of them?

Also, I’m aware that #1 is sometimes a host issue, so I’m on hold with them as well. But I wanted to see if this behavior sounded familiar to you, particularly the errors in #2.

Thanks!
