our website is on social engine 4.1.7.
the website is customized in many ways and uses the facebook registration for the sign up process.
the problem is that the website is not compatible with the INTERNET EXPLORER browser.
new visitors of the website do not manage to register using the "register with facebook" tab.
they also cannot choose "subscription" packages as they cannot click on the tabs.
when our vendor tried to solve the issue, the browser became compatible but the registration process started misfiring.
the project is urgent and hence quote for a time bound solution.
the quoting vendor must understand that there will be a 10% penalty per day of delay to deliver project after committing on a particular date.
also only those people should apply who have knowledge of social engine 4.1.7.
