It was recommended that I increase both my PHP Memory Limit and PHP Post Max Size. I was able to increase the memory limit just by upgrading from PHP 5.3 to 5.4. However, I still need to increase the memory limit, and I am trying to follow the Wiki instructions (http://wiki.dreamhost.com/PHP.ini#PHP_5.3_.2F_5.4).
I go to AjaXplorer (WebFTP.dreamhost.com), but I cannot seem to locate the home or my username directory in order to create the .php folder there. If I try adding a folder in the main directory (FTP Host) or one of the subdirectories (e.g., my domain name), I get error messages about forbidden or cannot access. What am I doing wrong?
