Hello Mate!
This issue happens on a few servers like yours, So i recommend you should enable the SEL and combining the Mod Rewrite , then the site has smarter links and shorter links .
1) Access the Global Configuration => Select the yes option for the the UseApache Mod Rewrite parmater.
2) access your host via the FTP and rename the htaccess.txt file to .htaccess
Note: you need checking: Does your server support or enable the Mod Rewrite or not? with what you did following my guide, the SEL does not work, you should contact the hosting service to check the issue with the Apache Mod rewrite
