New To Module Development - How to Create Module Controller

[oc1300]

Hello all,

 

I made a test module using the following tutorial resources and code:

 

http://developers.prestashop.com/module/05-CreatingAPrestaShop17Module/02-CreatingAFirstModule.html

http://developers.prestashop.com/module/05-CreatingAPrestaShop17Module/04-AddingAConfigurationPage.html

http://doc.prestashop.com/display/PS16/Adding+a+configuration+page

 

Trying to change configuration values through the Configuration Link works perfectly. However, I added a tab for the Configuration page (so that a link displays on the left sidebar in the Admin area), and changing values there gives me an "Invalid Security Token" message.

 

After receiving this message and clicking to continue anyway, no values are saved/changed. What can I do to fix this?

 

Thanks
