As I was tryin installing some new plugins/addons I've somehow "managed" to disable File Manager functionality within the system. It's strange as all images in my test site are working properly. Then, I've overwritten whole concrete directory, no success. Uninstallation of all plugins also didn't help. All I see when I click on FileManager within system is just a title File Manager, nothing else. Is there some proper way to overwrite some files in C5 structure to "repair" it? Am using 5.4.1.1 /
