I was having the following problems:
1. The next month and previous month links were not showing up on the Large Calendar, though they were in the admin panel.
2. My events were not showing up on the Large Calendar, but they were in the admin panel.
I too am using a custom theme. Thanks to ronbme for suggesting the Theme Test Drive plugin. Sure enough, switching to the default theme solved the problem. To troubleshoot, I started replacing the default theme files with my custom theme files one by one, and testing the results using the Test Drive plugin.
Solution:
1. I had a style element that was hiding the previous and next month text. To fix this, I added the following CSS to my theme:
#content #calendar_wrapLarge h2 span {
display: inline;
}
2. In my header.php file, I had removed the following code:
<?php wp_head(); ?>
When I put it back in (just above the </head> tag) the events showed up on my Large Calendar again.
I hope this helps others solve the problem. I don’t believe there is any problem with this plugin.
FYI I’m using WordPress 2.5.1 and Events Calendar 6.0.11
