Here’s a quick tip for you — if some function in the WordPress Dashboard (especially WP v2.7) isn’t working for you, or if you make some changes to your WordPress theme and you’re not seeing them on your live site, clear your browser cache!
This one simple thing can solve a number of problems for you. Browsers are weird animals. In the name of speed, they cache (store on your local computer) many of the files and images that make up a web page. Sometimes it doesn’t know when to ask for new files from the web server of the site you’re visiting.
If you’re on Windows and you’re using Internet Exploder … er, Explorer … go to Tools >Internet Options and click on the Delete button in the ‘Browsing history’ section. In the dialog box that opens, click the ‘Delete files…’ button in the ‘Temporary Internet Files’ section. Follow the prompts to delete the files. Close and restart IE.
If you’re using Firefox (and you should be!) click on Tools then Clear Private Data (or hold down ctrl and shift and hit delete). In the dialog box, clear all of the checkboxes except ‘Cache’ and click OK. Close and restart Firefox.
Do it twice! Only the browser gremlins know why, but I’ve found that sometimes once isn’t enough to completely clear the cache files.
