Can´t Upload images on Parralax

Good afternoon
I have the site made a few months ago and when today I went to try to change some images of the site, an error arises.
When I try to change the photo of Parralax, when I click the “Upload Image” button, the page resets and does not show the photo gallery.
I already have the latest version of Wordpress and deactivated all the plugins except the two of colorlib, as you can see in the attached images.

How can I solve this problem?

Hello there,

I hope you are doing well today.

Please try using the following plugin to delete your WordPress cache.

it may be the case that you need to increase your upload limit in WordPress. Please have a look at the following article explaining how to do so:

Best Regards,

Good Morning

Thanks for the help, but none of the procedures helped resolve the issue.
However, I remember that when I started the website construction, I used the www / wp directory, but in the meantime I decided to move the site to the www root directory.
Could this be the problem? If so, how can I change the paths?

Thanks again
