Fixed, need to enable PHP Multibyte Regex Functions on your server.
Thank you for the reply Rikard, will see if that stays after the next update.
This works, but every time I update the theme it changes back to Kriesi. How can I prevent this happening?
Great thanks a lot for your help!
Since updating to 4.0 I am no longer able to add Media. When clicking on the ADD MEDIA button, nothing happens (not error message, no action). When I try to set a Featured Image in a Blog Post, I am taken to a new page with the media options, but then a blank page appears after uploading. (Previously when setting the featured image, a Lightbox window opens, but now I’m taken to a new page that opens in the current tab). Other sites not updated to 4.0 are working fine. I’m using 2.9.1.
**Updated to 2.9.2 and can now set featured image and add media is back.
