Are you having the same problems with both of them?
I'll also ask if you have installed the latest version of Data Bridge [1.0.6] (and Design Extender [1.1.0] if you own it as well?) Also, did you uninstall the previous versions before you installed the new ones, and install them after eCart or any other legacy extensions that are NOT included in DB or DE?
Yes have installed latest version of both and also i delete the config folder before installing after deleting the folder i also checked to delete them from the extension manager
