Hi Rick, thanks for your reply.
My question is: What to replace? The new server have the same configuration than older, same domain
name but is running newer version of PHP and other services.
The strangest thing for me is that some images are loading and others are not.
I see that almost all the images that do not work are related to the theme that I am using. For example, it does not load the favicon well and neither do the user images.
I have also seen problems in some images on the front page
related to the theme.
If I copy the url of an image that appears as broken and try to open it in a new tab, it stays loading for a long time and does not appear.
It is as if something is wrong in the response to the images. Some problem with permissions or similar, but I can't see anything in the logs that tells me what is happening.
It is very frustrating because this installation worked perfectly and I have never had a problem.
I have tried to enable debug mode in Moodle, but I don't see any error messages when browsing the platform. Do these messages appear on the screen or are they stored in a file?
In the previous VPS I also had two Wordpress installations. I have done exactly the same process to transfer them to the new VPS and both work perfectly.
I do not understand why with Moodle it is not like that.
I don't know where to start or what to try to try to fix the problem.
Please, I need your help. What can i prove?
