I'm having trouble uploading PHP or CSS files via SFTP or making changes to a file via SSH to our Ubuntu server running Apache.
When upload the initial few files the server updates correctly and is reflected in the website via a browser(In my case it is Chrome). After multiple rounds of updates the website stops reflecting any changes to files.
This is the crux of my problem. No matter what method I use(WinSCP, CyberDuck or even nano in SSH), once the website stops updating not matter how much I modify a file it stops showing in the website. I don't understand why this happens if someone could explain it to me I'm sure the internet by and large would be very appreciative as there is next to nothing when it comes to this issue online, apart from timestamps and accidentally modifying a different file. I've double checked all of that and even got a 3rd party(a mate) to test and was able to replicate the same issue.
I used to use filezilla and this issue only popped up a few times. Now that Filezilla is no longer safe to use I've resorted to WinSCP and CyberDuck, however the problem is now so prominent that I cannot change anything on the server now.
I realise this question might be a silly blunder on my part, so any advice is most appreciated, I will try any suggestions placed here.
