Hello, too may posts for one day, but:

There is a category link within the MyLinks "Random Link" block that when clicked gives a 404 not found error for category.php not found.

The error is valid. There is no category.php file in the module directory.

Edit:
I found that category links do work form the main interface, but they are calling viewcat.php instead (successfully). It looks like someone never changed this block code to call viewcat.php instead of category.php. I should have the fix posted tomorrow.

To fix the previouly mentioned bug

Go to line 50 of /mylinks/blocks/mylinks_rand.php

Replace this:
";
