This is never happened with me before, neither with my friends.
A colleague wrote an article about hosting companies, and I made the cover photo. After one hour of the publishing, I made a small change of the cover photo, and I uploaded the new photo to replace the old one (that was published before one hour), and here is the surprise: NOTHING HAPPENED, this change took effect after about 24 hours. So this is what I did before coming to here to get your help:
1: As the service on the website is managed by Wordpress CMS, we tried to install empty cache plugin, but after testing, nothing happened. The plugin confirmed that there is no cache.
2: As we are using CloudeFlare, I tried to purge everything, because I doubt that maybe the problem came from CloudeFlare caching system. Nothing happened.
3: I cleared all the cache of my browser, and tested the website from the same browser(Chrome), also from other 2 browsers ( Explorer and Firefox), and nothing happened.
For example, we had made a small CSS change, after uploading the file on the server, nothing happened, so we left the experience till we discover the problem. In the morning, we discovered that this CSS change took effect…
In fact I sent them a message, as this is a cloud hosting (something like Dedicated Server), and I’m waiting their answer. But I have root access to my server, so what is mean cache delay on a server ? maybe I can do something
I thought it might be the case that they serve the visitors from a saved copy of your server, and that copy gets updated every 24 hour. (Maybe that is a part of their security system?) The support should know.
I understand your root access see the updated files as you change them, and when you deleted them you could still get them as a visitor?
Ah no, I mean I can access the root if needed. But I was using Wordpress, but till now the problem didn’t come from the wordpress, maybe the server. I will give you soon the answer of the technical support. Thanks again for your support
