I was previously using 2.3.4 of silverstripe with a theme that worked with a module that I created e.g.
mymodule
themes/mythemename_mymodule
However after upgrading to 2.4.0 the mythemename_mymodule no longer works (I rebuilt the project to see if this would fix it). However on my development machine all is fine and works as it should. The issue seems to be affecting my staging server and cannot figure out what the issue is. Ive rebuilt the project on my development machine and still works correctly so something is different on the staging server but unsure as to what.
Has anyone run into similar problems ? What I do know is the manifest-main file doesnt recognise the mythemename_mymodule directory at all which im scratching my head about as file permissions are fine.
