In my attempts to use version 2.0 of WordPress one of my greatest frustrations has been that many times when I go back and edit a post the edit function does not pull up the version I just saved but instead a cached copy from before my changes.
When I first noticed this I went searching for a fix but could not find where anyone had posted having the same problem. I have been meaning to go look again and if I didn’t find anything then to post a message at WordPress asking for some help.
Just today I noticed a new plugin available, Cache-Flush, which adds an item to the Admin|Options menu allowing you to manually flush the cache. His site does not say much about the plugin except that “it will allow you to manually flush the default WordPress cache”.
So now when I see that a cached copy without changes has been loaded I can just open the options menu and flush the cache. I hope WordPress gets this fixed in the next update – I am guessing that they left out the call to flush the cache for the single post when you ask to edit the post.
Another good use of this plugin is that the cache is stored in the wp-content directory. I routinely back this directory up since it has my themes, plugins (with mods), images, etc. Now I can flush the cache before I make the backup since there is no reason to backup the cache. Again, wish they had put the cache in a different directory but, hey, I was not asked.
