I tried to upgrade the browsercms project to latest version (browsercms 3.5.3). But it shows the error like undefined method 'cms_connector_path'. Any one have idea to get rid of it?
Can you provide more specifics? i.e.
With upgrades, many of the preexisting path helpers have changed to reflect the new Engine behavior. It's possible there is some custom code in your project that uses the helper. With engine, paths in views should be prefixed using the engine name, like so:
Verify whether you have views in your existing project that were copied from the CMS project that might need to be either deleted (since the core project has updated them) or recopied and edited (if you tweaked them).
