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!
Thank you mibuthu, I look forward to it.
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.
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.
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.
