I have a serious problem with all the three different wordpress installations i've installed on our server (Linux/Apache)
Many times, after going to the admin page and trying to edit data (eg. edit posts), I'll find that clicking the 'Edit post' button will not update the data. In fact, it may even return an old copy of the data, thus deleting all the changes that I just made!
I find this recurring very often. If I ignore the refreshed forms and go view the site, the changes were saved. But the forms were not refreshed.
To explain clearer with an example:
I edit a post that was made. Say, I typed a whole chunk of new verbiage, and I click 'Save and continue editing'. The form that is presented shows the post with content as before! If I click save again now, the content would change to before the new content I just added. However, if I don't save, then its ok.
You can see how this would be very frustrating to work with.
Another example would be when I log out. I'm frequently visited by the same page as if I'm still logged in. Or when I add a new link, but the returned HTML page shows the old form without the new link (even though I know the link is now in the database: I can see it on the site).
I have very little knowledge of web servers but am guessing it has something to do with old content that is cached. Or is it the database that's somehow returning me cached data that's not updated? Please help!
WordPress is just such a cool system to work with, if only this problem can be resolved! Thanks in advance.
