po files have mistakes

More than using poEdit, I prefer to use the WordPress plugin “Codestyling Localization”.

When translating languages files for the Events+ plugin, I see this warning:

“Warning: The actual loaded translation content contains mixed textdomains and is not pure translateable within one textdomain.

It seems, that there is code contained extracted out of other plugins, themes or widgets and used by copy & paste inside some source files.

The affected unknown textdomains are: wpmudev, wdfb, agm_google_maps “

I believe this must be corrected immediately as makes some strings untranslatable and useless.
