[SOLVED] J4: Error massage "exif_read_data" function is not available

I downloaded and installed J4Beta4.
If I open an event list of Venue list, I get an error : "exif_read_data" function is not available
Did I Forget something?

Did you follow the instructions?

I have a fresh installed J4 test site. And installedJEM 40b4.

The GitHub installation remarks are :
“Download the installation package here from the repo and install it ”
That is all I did. Did I need to do something more?

I guess that you have created an event, Does event have any image?
This error is generate to read exif data of image file.

The error message occured ween I created a venue. Thuis venue does have an image.
It also occured when I added an event. This event also has an image

@McKillo: I remember, we had earlier this, but it was resolved. After was the change with the blank images. Is it because of this?
