Memory error- please help


2 days ago my site: showed a memory error…only shows up after you login.
does anyone have any suggestions?
memory limit shows 90m and apparently i am using it all.
i have looked into it and some say to up the memory in the php.ini file. not sure where that is or how to edit it.
do you think if i update the joomla files {i am still running 1.0- totally outdated} that is will help in the memory usage?
i contacted dreamhost- they took 2 days to respond with links to wiki posts…mostly confusing me more. lol

any helps, suggestions or links to help would be wonderful.
My site has over 1000 members and to have it not working really stinks! i am stuck and not sure what i should do next.

thanks :slight_smile: Becky
