Invalid Image Dimension Error Message at the product page after installing the extension
imagecreatetruecolor(): Invalid image dimensions in /home/xxxxxxx/xxxxxxxx.com/system/library/image.php on line 105
This issue happens when you fail to setup the extension and do not save the settings. It is very important after installing the extension via extension installer, you should go to the extension and setup the extension properly and save the settings.
The above error occurs when you leave the image dimension fields empty in the extension settings or when you do not save the image dimension value.
