I’ve recently upgraded a client’s system from 6.5.2 to 6.6 which contain a custom control (rx_cascadedropdown). After doing some testing I noticed that the content type that uses the control still opens but with the following message:
“The following fields have invalid controls associated to them (field1, field2). These controls have been replaced with sys_Editbox.”
Is there anything else I need to do post upgrade to get the custom control to work?
