Yes, sorry for not posting my site earlier.
The guest download was just an experiment, i'll be switching back to accounts only, crashing occured even when gust download was not possible
Depends, sometime site crashes after one file other times after 3,4,5 files.
I was thinking if there is an option in cpanel to limit usage to the I/O usage so it does not go over, i don't have an issue with my site loading slower i have an issue with it crashing, it's not a very good user experience.
Or some settings in Invision community's Admin CP so i can take the load off the site ( read / write less ).
