Actually scripts can write to database when its set to 755, with the host I use. My smart thumbs works just fine, and it rewrites pages quite often, and stores thousands of pics in a database. The only problem is when a folder get changes to 777, is that its scrips are no longer usable. I need trade pulse to stop chmod my folders.
The host I use is a bit weird and they explained that I can have scripts I have uploaded write files when set to 755, and so far it has worked. Only when trade pulse set folder to 777 do I have problems.
I have removed trade pulse and have had no problems since, However trade pulse is very good, so I still what to use it if anyone has any suggestions.
Thank for your reply thoe, I understand that 777 is the norm when needing write permissions.
