conflict between Geolocation"GeoIP (Php)"& Branding settings (no replies)

Hi,

In Geolocation, when i selected "default", piwik can upload and display custom logo and favicon correctly.
In Geolocation, when i installed & selected " GeoIP (Php)", piwik can't upload and display custom logo and favicon.
I re-installed version 2.14.3 in new server, the conflict persisted.

I found that after installing GeoIP (Php), there were many files added under /mic, see attached file.png

When i deleted those files under /mic, custom logo and favicon can be uploaded and displayed correctly.
When i uploaded those files again, custom logo and favicon can't be uploaded and displayed correctly.
