Hello
I have added two plug ins Thumbnail Upscale and Thumnail Regenerate which solves the Thumbnail issue but now it has caused an issue with uploading images. Each time I upload images I get a stack of error messages. If I deactivate the plugins the issue disappears but I am left with incorrect Thumbnails. Has anyone else experienced this? Example of errors below
Warning: imagecreatetruecolor(): Invalid image dimensions in /home/sshopmin/public_html/wp-includes/media.php on line 2108
Warning: imagecopyresampled() expects parameter 1 to be resource, boolean given in /home/sshopmin/public_html/wp-includes/class-wp-image-editor-gd.php on line 182

Hi,
Not sure how the plugins conflict with WordPress’s imagecopyresampled function but if you’ve regenerated thumbs and solved the thumbnails issues then you can disable thumbnails regenerating plugin because you don’t need it anymore as the thumbs will be automatically created when you upload an image.
The thumbnail upscale plugin is also unnecessary if you upload images large enough to fill the largest thumb container you’re using so I suggest you consider this and not use those plugins.
Thanks
This usually happens if
a) you don’t have enough memory allocated to WP
b) you’re trying to use a file format not supported by WP media manager
c) trying to use local image thumbnail generation at same time as external tool like Jetpack photon
d) trying to use site through a rewrite service like Cloudflare, etc.
e) bad file naming — like more than one dot, spaces, high ascii characters, missing file extension, etc.
