I'm having problems getting a Paypal button to work on my site, and in order to test the issue thoroughly, I created a duplicate of a page with a button that works. When I say 'created a duplicate', I copy/pasted the entire code from one window of Notepad ++ to another. They should be identical. They are in the same folder of the website.
In the duplicate, the Paypal button, as well as the pound signs, don't work.
The original page, which works, is at http://www.sidekickbooks.com/laboratorio.php
The duplicate is at http://www.sidekickbooks.com/buttontest.php
I should say that when I click to 'view source' on the website, the pound signs have been replaced with '+£' (which is probably linked to the Paypal button not working). However, in the file I'm uploading, these are clean pound signs. I have no idea why, on this .php file and not the other, the substitution is being made.
Any help appreciated!
Its a character encoding problem.
