Immediately after uploading we get a critical error (see screenshot), We also tried adding some code (https://wordpress.stackexchange.com/questions/130203/limit-image-resolution-on-upload) that limits the resolution for image uploads. This works for files uploaded directly via media library, but it doesn’t seem to work for the Avatar privacy’s (front-end) file uploader, we still get the critical error when uploading that file.

Do you also get an error when trying to upload one of the two example photo’s?
