This fix exist from a long time now, version 1.1.6, so first, which version did you run actually ?
If not 1.1.13, consider upgrading to it also 
When you are reporting a problem, be sure to provide us all needed informations. This issue, as stated by @Athar and @kurgans, has been already addressed. Thus, we must really know which version you are using. Also, when you are reporting a problem, it's always a good idea to attach the relevant logs from /var/log/imscp which are filled only when the debug mode is enabled in your imscp.conf file).
Thanks
Sorry for the late response. I'm running 1.1.5. 
Are there any problems upgrade to 1.1.13 from my version?
There shouldn't be any problems, but you should do backups before upgrading! 
Same as Ninos: backup is the base of any systems anyways.
And for your information, I did this update (with some personnal modification of the installer, but this didn't change anything in the result) from 1.1.5 to 1.1.13, all good for me
Upgraded. All seems to be working Thanks guys.
Good, now enjoy i-MSCP and next time, try to do some search before posting (as this issue was present and take me 10 seconds to find it and Nuxwin solution )
