Hello, I'm using prestashop 1.4.7. Not all modules were working so I decided to delete cache and compile. Now I'm getting in blank screen in FrontOffice. Backoffice is still working correctly. Here is a part of the message I get, wen I'm entering FrontOffice. Warning: rename(/tmp/wrthvnEnO,/var/www/html/prestashop/tools/smarty/compile/b3dc123b916469299d20c20b168e27ac1b158ffd.file.blocklanguages.tpl.php): Permission denied in /var/www/html/prestashop/tools/smarty/sysplugins/smarty_internal_write_file.php on line 48 Warning: chmod(): No such file or directory in /var/www/html/prestashop/tools/smarty/sysplugins/smarty_internal_write_file.php on line 50 Can someone please help me? Thank you, Jan
