My thumbnails don't generate on their own since upgrading to PHP 7.3

[Ed Kiefer]

I'm running into this problem also. My thumbnails don't generate on their own. I have to upload them manually. I just upgraded from PHP 7.2 to 7.3 and now I'm receiving this error. I can still add photos to the product, but it doesn't generate a thumbnail.

This is the only issue I've had with PHP 7.3. Other than this my site runs great.

You forgot version VM, sure

is the gd library enabled?

I believe it still uses it.

Usually you have to configure each php version on server

VirtueMart 3.8.8
I just got with my host and they enabled the GD library. The errors are gone but the thumbnails still don't generate on their own.

[pinochico]

after enable you try vm tools for creating thumbs for existing images - tools you can use after setup in configuration

dynamic thumbs turned on?


they are generated when you view the frontend
