I am pretty sad that most of the plugins are currently outdated and not being updated to Framework 5. Is there a way to update plugins myself? There are alot of errors if i were to use old plugins ( Color undefined ) .
This is, unfortunately, a problem that exists with a community of developers who cannot provide the same level of assistance as the core plugins.
Version 5 of the Framework brought big changes to how CSS operates in Adapt. These may have caused breaking effects to many older plugins.
As Ailiniyazi said, it may be as easy as just going into a bower.json file and change the framework line to: "framework": ">=5"
If the plugin is still not working it may require a change to the code. Luckily many Adapt community developers are keen to help if a problem exists. You can report an issue on the Github issues page on the plugin and the developer should be able to assist you.
Hope that helps!
