Hello to our friendly forum,
I was uploading an image to my site (www.deploymentlessons.org if you need to see it) and was given an error message. I was surprised since I had just uploaded an image on another page earlier today.
Warning: imageantialias(): supplied argument is not a valid Image resource in /home/deplmet9/public_html/wp-admin/includes/image.php on line 44
Warning: Cannot modify header information - headers already sent by (output started at /home/deplmet9/public_html/wp-admin/includes/image.php:44) in /home/deplmet9/public_html/wp-includes/pluggable.php on line 390
Could anyone tell me what this means and how to fix it.
Many thanks, Deploy
