Some bugs

Hello, i know you will release a new version soon, i just have seen some bugs

I have set up a fundraiser with goal to 5 000 €, when i update it, it goes to 500 000 €, and if i update again it goes to 50 000 000 …. It’s the same thing with rewards.

When i try to pay with paypal i have this error message

Fatal error: Cannot use object of type WP_Error as array in L:wampwwwawp-contentpluginsfundraisinglibgatewayspaypal.php on line 141
