I need help troubleshooting my issue. I don't know what to look for. Magento 22.214.171.124. For what it's worth, this issue is probably related to the extension Webtex_CustomerGroupsPrice.
When I go to Customers > Customer Groups then I click Add New Customer Group, the page
Then I type in a group name and hit Save. The next page is:
and I get a 404 Not Found error from the frontend theme.
I have tried disabling the extension Webtex_CustomerGroupsPrice which does not change the symptom. I am just beginning to learn how the database works so if it's as simple as fixing a row in a table I can do that.
A rewrite exists in
<config> ... <global> ... <rewrite> <customergroupsprice_customer_group> <from><![CDATA[#^/admin/customer_group/save/#]]></from> <to>/customergroupsprice/group/save/</to>
Is this the issue? Why isn't that rewrite taking place? I have no idea what to do. Where should I be looking to troubleshoot this?
