We have a website whose home page is http://bigbird.comp.nus.edu.sg/pmwiki/farm/appl/index.php As you see, it is based on pmwiki.
We find CSS, JS and other resources are loaded over http. That is because links generated by pmwiki's php files are prepended with http://. We want to remove the prepended http://. Links will become like:
<script src="//example.com/script.js"></script>
Which pmwiki's php files should we modify?
