I cannot upload images to LimeSurvey Professional server when editing survey themes. The error notification that appears is: This file is not supported image - please only upload JPG, PNG, GIF or SVG type images.

I've tried various types of JPG, PNG & SVG images and the results remain the same.

Please somebody help me...

Here I attach the image file I tried to upload

Best is to contact www.limesurvey.org/customer-support directly
