Maybe someone already saw an
[...] <field id="provider" translate="label" type="text" sortOrder="100" canRestore="1" showInDefault="1"> <label>Provider</label> </field> [...]
Any ideas what does it mean?
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
You can show Use system value check-box to system configuration by canRestore=”1″ property in system.xml
In your config.xml file, you can specify default values for the admin configuration form that you created in system.xml. If a user manually entered a value in one of those fields, they can reset the field to the default value that you specified in config.xml.
