To add to my last post...

There was a second error on the Debug log along with the one I posted in Post #233 above.

It is:

PHP Warning: foreach() argument must be of type array|object, null given in C:\wamp64\www\new2121\zc_plugins\InstantSearch\v4.0.3\classes\SearchEngineProvid ers\MysqlSearchEngineProvider.php on line 133

Hopefully this gives the full picture of what I'm experiencing.

Not sure why the plugin worked well in the stock Zen Cart v.2.1 with demo info in the database, and when I then added my Zen Cart v.1.5.8 database (ran the zc_install after to update the database to v.2.1) the plugin doesn't work and it throws this error. Adding the database was the only change I made....just for full disclosure.

One thought....when installing the plugin, does it happen to automatically run some sort of SQL statement that now needs to be rerun somehow to incorporate it into this database??
