Ok, I see your screenshot but I do not know where I have to change that. Where should I increase the storage value limit? on the server in a php file? Unfortunately, your screenshot does not show what you looked at.
Today I created a local environment with xampp and tried to upload an image with the imported backup. I have the same problem there. But at least I get a recommendation there:
"Notice: Trying to access array offset on value of type int in D:\xampp\htdocs\hm-courses\administrator\components\com_guru\models**guruauthor.php on line 31**"
What exactly do I have to change where? Unfortunately I am only a user and not a professional and I am grateful for any help in solving the problem!
