Hi all,
in PS 1.6.0.6 i still got the problem but using Filezilla to recursively change permissions, 755 for directories and 644 for files, Paypal works.
Looks like it will be fixed in 1.6.0.7 (http://forge.prestashop.com/browse/PSCSX-1487) but I do not know if this fix will change also modules already updated (with 777 permissions ) or only the new ones.
Should I change all modules permissions to 755 in directories and 644 in files?
Or there could be modules that need different ones?
Thank you.
