Product Update Not Working For Converted Database Products

[shrimp-gumbo-mmmhhh]

VERSION (NEW CODE - CONVERTED DATABASE)
----------
v156a

PLUGINS
----------
Encrypted Master Password 2.3.1
Numinix Google Analytics
USU 2.216
USU 2.217
USU 3.0.0-beta3

PHP Version: 5.6.40

[FONT=Verdana, sans-serif]This appears to be occurring with all my products. I pick a product. Edit it.... Change the quantity... then PREVIEW.... the result is that it gives the product name but doesn't give anymore of the preview.... i am unable to save the changes (No buttons). I uninstalled USU to see if this was what was causing the problems and it is still behaving the same way.

In uninstallation/installation, the admin/product.php file was modified away from the ZC 1.5.6 version of the file. Suggest restoring it or incorporating the differences of previous USU versions of that file with the equivalent file of the ZC version associated with USU.

(in other words incorporate the changes made to support the plugin if any are necessary.) reportedly the newest version of USU doesn't need to touch that file.

What @mc12345678 said! The upgrade directions for USU v3.0.0 identify that you'll need to hand-edit previous versions' changes to various core files (https://github.com/lat9/usu/blob/v30...ade_from_v2.md) to remove those changes.

With the plugins you list, I believe that it's safe to simple replace all the files identified in that document with their Zen Cart 1.5.6a as-shipped versions.
