In our installation of Moodle, we're running into the following problem:
Sometimes (and it's maddeningly inconsistent as to its occurrance) when a visitor comes to the site it will "hang" - be nonresponsive, save for little more than the contents of the <title> field.
Clicking the [Stop] button on the browser, followed by [Reload]ing the page, "convinces" the system to load everything successfully.
The problem has been there since our initial install of 1.1 - we've since upgraded through 1.2 to 1.21 to 1.3 - though it seems to have become a bit more pronounced since upgrading to 1.3.
Other possible factors: The site is on a shared server (albeit one of our own).
Any thoughts on how to keep this from happening would be greatly appreciated.
