Wordpress Theme is not Responsive to Updates

I have a WordPress theme that's installed and has been running fine for a while. I recently needed to update the theme itself, and I did so use the built-in theme editor. Upon reloading the site, the theme changes are not presented in the markup.

Removing the index.php file from the theme or changing its name results in a blank page as expected, but removing all contents of the theme's index.php does not have a similar effect. In fact, the WordPress installation continues as if I had not made index.php blank.

I have no caching plugins installed, Varnish is not present, memcached is not in use at all, and neither is APC.

I attempted upgrading all the plugins and WordPress itself. The raw-html plugin I have installed failed to update with a fatal error about an include on line 16, but that include was not present. The update worked fine when I renamed th开发者_StackOverflowe plugin filename though (from raw_html.php to raw_html1.php).

I have found that the cache is the biggest issue when dealing with WordPress; Even when you don't have the cache enabled for the site. I have found that if I make the edit and look at it later, the changes have been updated.

This is not ideal for development.

Sometimes a plugin will have some type of a caching issue (even if the plugin doesn't deal with the cache) that causes the problem.
