ERROR: Failed to find flength file

[tamersherif]

When i try to upload a video i get the error "ERROR: Failed to find flength file" then it redirects to another error
Software error:

mkdir /templates_c: Permission denied at ubr_upload.pl line 111

I asked my hosting support (Bounceweb.com) they told that this issue is related to mod_security which is not installed on their servers here's my phpinfo phpinfo()
Is there any alternatives?
Thank you.
