Can only write Captial Letter in the topic title field
When I write in the topic field it shows only capitol letters. After "add topic" the letters are normal. Same in the login field. Please see attack file. Thank you!
Could be your theme capitalizing the titles. Can you try an other theme for a while?
Well since this a theme related issue, i have no idea how to solve it.
A long shot is if the capitalization is done via CSS, then find the "upper" in your theme's css and remove it.
