Unknown error

The widget part is normal. Please proceed with the steps given:
Goto the admin page Appearance -> Widgets, choose the event-list widget and press save. Afterwards it should be working again.

The problem on the admin page I already mentioned. It seems to be a problem when using permalinks.
I’m already working on it and hope I can release a fix soon.

Thank you very much, I’am right before a deadline

I have fix this issue now in the development version.
Can you please try it with this modifications in your installation?
Would be good to know, if this also solve your problems.

I will release an updated version tomorrow.

I said Victorie to soon. ?? The widget shows it content but I can’t change anything or I get thit error again

Warning: Cannot modify header information – headers already sent by (output started at (website)/wp-admin/includes/template.php:1698) in (website)/public_html/oo/wp-includes/pluggable.php on line 896

Succes with the oncomming update!

I think I’ve found something valuable; when I add a event the default date for today is “3 januari 2014” when I change this to “3 January 2014” is works. I tested this on the downgraded version 0.56

I have release a new version with some fixes now (0.6.1). This should fix the “Cannot modify header information” bug.

I will have a look at the date issue, you last info is a great help.
Did I understand it correctly that you also have this problem in the old version 0.5.6?
You can also have a look at this thread, but I think your problem is different.

Is this the same problem?

When I modify an event the next error occurs:
Error: Event “Test” (id: 11) could not be modified.
Only when I change the start-date, the event is modified with no error. I tried to change the WordPress date format, but that has no effect.

Sorry, 0.6.1 does not solve my problem. The only way I can change an event, is to change the start date of the event.

There are no date fixes in 0.6.1. I will do more testing and hopefully find some fixes for the next versions 0.6.2 or 0.6.3.

I wonder whether a solution is found already. I can’t explain to users why they should change the date twice when they modify the text of an event. I hope for a fast solution.

In the next version I will include an option to allow specifying a manual date format for the event form. This should allow easier testing and should also make it possible to specify a standard format to make it working until I find a solution. Probably I can already identify the problem.
I hope I can release the new version next weekend.

Thank you mibuthu, I look forward to it.

I have done a complete rewrite of the date handling in the new version 0.6.2. All date issues should be fixed now.

Good news! I tested it on my test-site and the problem is gone.
I just installed it at the production-site and asked the users to test it.
Thanks for this fix!

I have WP and plugins updated to latest version but I can’t get your plugin to work. When I try to add a new event I got follow message: Error: New Event “test” could not be added.
When I try to update an old event I got follow message: Error: Event “Testing” (id: 6) could not be modified.
Date format is set to “Y-m-d” but I have also tried “Y/m/d” without any luck. I also tried to reinstalled plugin but that didn’t help.
Please help me.
