Presta opsætning.....

ref http://www.elated.com/articles/understanding-permissions/
Owner (system bruger) kan Read,Write,Execute
Group kan Read, Execute
Other kan Read, Execute

rettigheder skal bare skrives binært, 1=rettigheden haves, 0=rettigheden haves IKKE
systemet = 111 => 7
Group = 101 => 5
Other = 101 => 5

Men giver det mig ikke problemer med noget funktion for enten mig selv i admin modulet eller for kunderne?

det burde ikke give problemer, ingen andre end systemm brugeren kan skrive i folderen, men alle kan læse og udføre filer der ligger i folderen

hvilke miljø er din installation lavet på ?? (windows, mac(kører linux), linux)
hvad står der i httacces filen, evt ovenliggende httacces fil som den arven fra??
kig efter noget med deny from


hvis installation er på en mac/linux er det mest sansynligt et rettigheds problem, prøv at sætte 755 på folderen

CHMOD
Changing file/folder permission on a Unix/Linux system is called a "CHMOD", after the command of the same name (see: http://en.wikipedia.org/wiki/Chmod – you can find an explanation of file permissions here: http://www.elated.com/articles/understanding-permissions/).
Giving files or folders a "write permission" is called "doing a CHMOD 755" or "a CHMOD 775", depending on the host.


Some hosts might require you to use CHMOD 777, although it is not recommended for anything more than a one-time need.
If you have to use CHMOD 777 in order to install PrestaShop, make sure to switch to a safer setting (for instance, 775 for folders and 664 for files) once you are done installing.
Read your host's documentation carefully.

Måske din host har aktiveret mod_security som default:

Selve httacces filen som ligger i min Presta shopmappe ser sådan her ud:

Det ligger på en Linux server med PHP
Jeg har lige prøvet at ændre folderen til 755 og det hjalp!
Men giver det mig ikke problemer med noget funktion for enten mig selv i admin modulet eller for kunderne?
