problems with tinymce + img_assist

Hi all,

I am trying to install tinymce with image assist, but have problems.

When clicking on the 'camera' button to insert an image, I get a popup with a 404 error, with the following URL

http://<mydomain>/<path_to_drupal>/sites/all/index.php?q=img_assist/load/tinymce

Looks like the image browser have got the path to index.php wrong. Could someone please help me find out how to correct this error?

Apart from this error, everything seems to be working fine. I can use tinymce, upload images, I have set permissions, enabled images in filtered html, enabled image assist, etc ...

Using:
tinymce-5.x-1.x-dev.tar.gz
img_assist-5.x-1.1.tar.gz
image-5.x-1.0.tar.gz

Thanks so much for your help!
