Bug Fixes for Woo-commerce Wordpress Shopping Cart

I have a bilingual shopping cart that combines Woocommerce shopping cart together with WPML. This project has 2 parts. The first is I have 3 small bugs I need fixed. (It is possible that more bugs will come up as we go and of course further compensation will be provided). The second part is a somewhat bigger bug fix to my Spanish shopping cart to get it to work. Bug #1: In Settings when I hit "+ Add Flat Rate" nothing happens and the dialog box that should pop up does not Bug #2: In "Upsells/Cross-sells" in the Product Data for individual items, when I try to search for items to add and I search nothing happens, the page simply refreshes. Bug #3: After translating some strings from English to Spanish, they appear in Spanish in my English checkout page Bug #4: FIXING SPANISH shopping cart: The cart does not work correctly right now. When I add items, the AJAX gif just continues to "spin" and nothing happens. When I try to checkout it logs me out. There are also some minor CSS issues due to Spanish strings being a bit longer then English default. I EXPECT WORK TO BEGIN IMMEDIATELY AND PROJECT TO BE COMPLETED WITHIN 48 hours MAX with payment released. Don't bid unless your ready to start ASAP or I will dispute funds if you accept and work does not begin immediately. Additional bugs and fixes beyond initial bid will be billed at $10.00 USD per hour. However, no extra further compensation will be provided above your bid for fixing the 4 bugs above. Good luck bidders :-) ATTENTION: Knowledge of Woocommerce Shopping cart and WPML plugin is recommended My budget is $100 maximum for this.
