"Platform Error" (Details attached)

Hello,

I'm currently having issues with various featres on my gallery such as errors when i try to upload files through the server, try to update with a watermark for certain albums, and other issues. What happens is a page appears named "Platform Error." I attached a notepad file of the error details, I don't know what it says so i don't know what to fix.

Someone please help me out. =) Thank you.
