I have read your project description, and i understand what's the problem. However i will need to examine your website more deeply to understand what's causing it. I have strong knowledge of Magento, and technologies used by Magento (PHP&MySQL, HTML&CSS, JavaScript, XML, ...), and over 10 years of experience in web development, and administration. If you have any additional information, or questions, please don't hesitate to post them by private message, thanks.
