Trying to renew my contribution to this awesome site using my phone. After I click my dollar amount and then click donate it opens PayPal in another browser tab, allows me to sign in okay, but then redirects me to a 404 error page not found. A quick search of this problem on Google makes it look like it is a website problem (pinsides) as opposed to a user problem (mine). I use PayPal all the time, on tons of sites, and this is the only time I've run into this. Ideas?
