Hi Alex,
I've duplicated, and fixed the problem for PR 29. That should go up today.
The problem is in the JavaScript file, so it's a tricky one for you to fix there - especially if you're not familiar with using the Gzipall Batch file to combine & compress the files. 
If you are familiar with using GzipAll then the error is in netweb.js
around line 904 you should see 2 lines of code
                ans = ans.replace(/%/,"%25");
                ans = ans.replace(/&/,"%26");
after these add a third line
                ans = ans.replace(/#/,"%23");
Cheers
Bruce
