Question

The styles for twitter and facebook icons are not applied on the [Communication options] detail after I upgrade to a new version

Answer

A CommonCSSV2 replacing client module ccontaining custom styles has been found in the configuration. The point is that the base styles have slightly changed and have been added in version 7.6.0, but replacing in the custom package does not let apply these changes.

To eliminate the problem, transfer the styles from the CommonCSSV2 base module to the replacing module and add the custom styles in the end. You can also delete the text from the "Source code" module tab - the styles contained thereon will not be applied.
