My client alerted me to the fact that the paypal module stopped working.
When I click on the button it just redirects to the same page.

Any ideas please???

oh and also another module on another site suddenly stopped working too.
This is the superfish module.
Could there be an issue with database?

The problems are probably related, but I'm not quite sure what could have happened. Did you change anything else recently?

I have been wondering what I have done recently that would have caused this. But regarding the paypal module; I only added more text to the article. The load function is in tact and displays on the page but somehow it does not redirect to Paypal.
By the way where is paypal location for? I never used it and it was working fine before. I looked into database and did not see any tables for paypalmodule. I have had issues before with a Wordpress Blog module. The main configuration always returned errors when trying to change anything. I ended up changing it in the dbase and never figured out what the issue was or how to resolve it.

I ran into the same problem and solved it by entering the paypay email address into the paypal location field as well.
