My b2evolution Version: 4.0.4
My users are experiencing a weird problem.
I have several blogs where one of the blogs is the main one where all the other blogs are aggregated.
Now when my users create a new post and choose a default category for their blog, randomly the category is saved incorrectly to the database and it's using the main category.
I have checked that the post is saved to the database but it not visible, because the main category is not used anywhere.
What could cause this?
Just realised that it was not actually saving the post.
The problem was with Internet Explorer 9.
The version of tinyMCE included with b2evolution is not compatible with IE9. I upgraded tinyMCE and the problem went away.
