Fix 2 Fatal Errors - Cannot use string offset as an array & other problems

I have 2 fatal errors in my store, the store was working fine before I upgraded from WordPress 3.83 to 3.9 now we have these 2 fatal errors down below. And few other things to be fixed. The store looks like it was custom made in WordPress Fatal Error #1 [login to view URL] Fatal error: Cannot use string offset as an array in /home/thenon8/public_html/wp-content/themes/nonprofittimes/[login to view URL] on line 62 When I went to the file, this was the line of code that has the error: <strong>$<?php print sprintf("%01.2f", $rows[0]["store_repeater_product_price"]); ?></strong></div> ========================================================================================================= Fatal #2 [login to view URL] Fatal error: Cannot use string offset as an array in /home/thenon8/public_html/wp-content/themes/nonprofittimes/[login to view URL] on line 84 When I went to the file, this was the line of code that has the error: echo "$ " . $rows[0]['store_repeater_product_price']; ========================== Error #3 Also on the landing page [login to view URL] there is usually 12-15 products listed there & due to these errors the products are not showing up on this page and that has to be fixed. And also on that landing page you can normally see the products in the WP admin landing page where you edit that page, the developer that made this store must have hard coded it where the products are loading from another file on the main store landing page. The products are in the store just not showing up. This may resolve itself when you fix the 2 fatal errors. ================================= Error #4 On the top main menu under Library I need to have the back color on the drop down list to extend over a few pixels past the text White Papers ================================= I need to have full documentation of what was changed, what dir, what file, what line of code was added or deleted or edited in a text file. ================================= Full payment will be made after everything is tested & working correctly to my specifications. This project should not take more than 1-2 hours to complete Please only bid if you have done this type of work before.
