We received the following note this morning:
One thing that I find a bit odd but am getting used to is that it takes a while for changes in the code, say in the sidebar, to show up on the home page, and sometimes on the other pages. That makes editing the layout a bit tedious. I assume it's a cache thing but changes used to kick in instantly on BlogHarbor, as I recall.
We install, and really would be upset if you deactivated, the WP-Cache plugin. This plugin dramatically speeds up your site and takes tremendous stress off the servers by allowing cached versions of your pages to be served rather than compiling each page every time it is requested. This plugin is your best friend, it's what allows you to rest easy knowing that if your site suddenly received a large volume of traffic, your site would be able to keep up with the demand.
Unfortunately, WP-Cache is not very smart when it comes to template changes or sidebar updates, and sometimes doesn't notice that you made an upate to your Presentation (don't worry, it works very well when you add new or edit existing posts).
So after you make some changes to your template, just go to your control panel and go to Options > WP-Cache. Scroll down and look for the Delete Cache button. Click it. Now your blog will be sure to output the most recent version of your template.
