You see, I had a strange error with some Laravel files that prevented me from accessing my page.
Note that the files that gave error were in the / tmp folder, so delete the entire folder.
After that, apparently the page worked again, but now I run into this problem:
I can not include photos in the form! The images that were already there are still seen and those forms that do not ask for images work perfectly. The problem is when I try to upload an image in a form. How do I fix it now?
