The file to edit in both Deluxe and 5.41 will be different according to what theme your using. On Web4URL.com, its in the index.html page of the theme.
Its very simple to edit... Just edit the index.html file, find where its being called, and change the call statement from 'max=50' to 'max='100' or how ever many you want.
Here's an example. In my theme, here is the statement being called:
Code:
<%block_tags_cloud title="Popular Tags" alphabar="yes" cat="0" max_item="50" template="block.tags_cloud_small.html"%>
and what I did was change it to this:
Code:
<%block_tags_cloud title="Popular Tags" alphabar="yes" cat="0" max_item="175" template="block.tags_cloud_small.html"%>
Whats in red has been changed between the two.
Like I said, depending on the theme will depend on where the block is being called. Its possible in some themes it will be called in the footer.html. Just find where its being called and adjust how many Popular Tags you want displayed
