thank you, this has solved the problem.
the default was 60M and 70M. i first changed it to 80M and 100M and it did not work. then i changed it to same as lsphp setting and it is now working at 120M and 150M
but is that not too high? what would be an optimum level?
is there any guide to tweaking/tuning lsws for best performance and optimum resource usage? i find that the help in the admin panel is helpful, but not very detailed, and leaves a less educated person like me craving for more
