Hi,
I’m running a Debian Server with Apache2 and PHP5.
On this server I have one WordPress multisite installation and also a normal installation. Both work fine since several years. However, since some time, users report the following to me:
Whenever they create a post, they can publish it fine. But if they remodify it or create another one right afterwards, the first post gets completely overwritten and “disappears”. (Create post -> Edit & publish it. Click “Add post” – an empty editor page is displayed. Edit & publish it: now that post replaces the first one. The first one is completely gone.)
I’ve seen this myself and tested reloading the post editor everytime manually, even if I see an empty editor page, using “Ctrl+R”. Miraculously, the problem vanishes.
So it seems, that this is some kind of caching issue. However, I don’t know if this occurs in Apache, PHP or MySQL. Has anybody seen similar things before?
I don’t use a caching plugin such as varnish on the server and my configuration files should be more or less the Debian default.
Cheers!
