CODEIGNITER | Help remove segments from URL

Hello , I have a problem setting up my current website's URL I bought a php scripts that handles some property listings , but the developer dosent respond to my emails. All i want to do is to modify how the url will behave. I managed to remove the [login to view URL] using the .htacces but from there on i can't find where to modify. The current URL of a property is : [login to view URL] The script is under a sub-folder : /i/ As I see the script has a multilanguage function /en/ ; every property has in its URL the /property/ and the /unique-id/ segments. Clinica-Unident-Tulcea is the property title ( from Clinica Unident Tulcea the title has " - " as divider ) I want to remove the multilanguage function ( not just from the url ) . Also from the URL is want to remove the /property/ and the /unique-id/ segments. After the modifications the URL to be like : [login to view URL] ---------------------------------------- As for other pages I have the fallowing : [login to view URL] I added a image that will explain the currect URL segments and what I need to remove and what to keep ( red for remove and green for the segment that I want to keep )
