Stock by Attribute v4.0 addon for v1.3.5-1.3.9

[snakes7575]

Hi everyone sorry for my english, I speak Italian I use google traslator, I ask you for help I updated installed zen cart 1.5.5e Italian version, I inserted the SBA module Version 1.5.4, I loaded all the files correctly and then installed from the path "stock_by_attr_install.php" after I ran the first "full upgrade install" script and immediately after also "non - stock DB Table Install" no error appears, at this point even if I try to create new articles with attributes if I go to the aka page SBA I see the search boxes but no list of articles appears, I get this message: WARNING: An Error occurred, please refresh the page and try again.
I had tested this form before making the transfer by purchasing a web space and it seemed to work, when I actually had to do the transfer it no longer works ... who can help me is 3 days that I try to get out of it but I can't, I'm not an expert, maybe it takes special permissions to folders?
