We’ve experienced the same problem with some modules, the only way we found was to check all error list, open every page or file that uses the faulty atlas theme, and changed it to another theme, this solved the errors, since the app store modules are from third-parties, they’re not all optimized and updated regularly.
There are some problems on adding modules on mendix projects, that doesn’t state exactly if it is compatible with another and so on. The only way is add one module, check if there are errors, if not, just commit and keep going. Try add other module, check if errors and go eliminating that. As stated before, the only way is the hard way, change layout problems found and see if that helps.
