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

All the files check out... thank you for the quick response.
It must be a db connection issue but it is a new db and I simply imported the data from the active site into the new db to test it. It stands alone right now as a new cart down for maintenance. I'll try and approach it from a db path angle and see if there is an issue there.

While the database install itself doesn't really care what version of ZC it is on and I realize the question relates to SBA, but if all that was done was to import the old 1.5.1 database into the database referenced by ZC 1.5.4 and nothing else, then there are other steps still to be taken such as updating that database to ZC 1.5.4. Otherwise, again, if the file stock_by_attr_install.php is accessed, that should at least initiate the "install" of the admin's configuration option to again return to that same menu. Then you can do an install/upgrade, or a remove (without removing the database table(s)) followed by an install/upgrade in order to make the other options/settings again available. There really should generally be no other modifications necessary to move from the older store to a newer yet still old store. If there are, please advise so that can either incorporate into the code to address automatically or incorporate into some level of instruction beyond a potentially "lost" post.
