The following message appears after adding new attribute(s) for a stock by attribute. The message does not appear when editing an existing stock by attribute. I have been able to exit after adding new attributes and on checking the site everything appears to be normal.

This message did not appear after installation of the Stock by Attribute module. The first appearance was after our computer technician moved ZenCart from one host to another.

Could someone assist with an answer please or please let me know where I should search for the answer. So far I have been unable to locate anything similar.
