Okay, I think the problem is the the Adcycle software. That's the software I use to run the ads on the site. Somehow, when I ran out of space on the server something went wrong. I am waiting for a reply from their support to fix that.
As for contributions, the company I used to collect money through credit cards went down, so I tool off their links. I don't think I will replace them for now, as it's a lot of hassle and all these companies charge hefty commissions. So, the "support the site" page now only lists the shop and such. Direct contributions would have to be made via check. If anyone wants to send any, please contact me via PM or email and I will give you my home address.
Thank you both so much for your wish to help!
